Substrate is normally connected to the most negative circuit potential, but can be floated. PRODUCT DESCRIPTION The design of the MAT02 series of NPN dual monolithic transistors is optimized for very low noise, low drift and low rBE. Precision Monolithics' exclusive Silicon Nitride "TriplePassivation" process stabilizes the critical device parameters over wide ranges of temperature and elapsed time. Also, the high current gain (hFE) of the MAT02 is maintained over a wide range of collector current. Exceptional characteristics of the MAT02 include offset voltage of 50 V max (A/E grades) and 150 V max F grade. Device performance is specified over the full military temperature range as well as at 25C. The MAT02 should be used in any application where low noise is a priority. The MAT02 can be used as an input stage to make an amplifier with noise voltage of less than 1.0 nV/Hz at 100 Hz. Other applications, such as log/antilog circuits, may use the excellent logging conformity of the MAT02. Typical bulk resistance is only 0.3 to 0.4 . The MAT02 electrical characteristics approach those of an ideal transistor when operated over a collector current range of 1 A to 10 mA. For applications requiring multiple devices see MAT04 Quad Matched Transistor data sheet. Input protection diodes are provided across the emitter-base junctions to prevent degradation of the device characteristics due to reverse-biased emitter current. The substrate is clamped to the most negative emitter by the parasitic isolation junction created by the protection diodes. This results in complete isolation between the transistors. REV.

Log Conformance Test Circuit LOG CONFORMANCE TESTING kT I C1 VBE = q In I + IC1 rBE1 - IC2 rBE2 C2 The log conformance of the MAT02 is tested using the circuit shown above. The circuit employs a dual transdiode logarithmic converter operating at a fixed ratio of collector currents that are swept over a 10:1 range. The output of each transdiode converter is the VBE of the transistor plus an error term which is the product of the collector current and rBE, the bulk emitter resistance. The difference of the VBE is amplified at a gain of x100 by the AMP01 instrumentation amplifier. The differential emitter-base voltage (VBE) consists of a temperature-dependent dc level plus an ac error voltage, which is the deviation from true log conformity as the collector currents vary. (2) A ramp function that sweeps from 1 V to 10 V is converted by the op amps to a collector current ramp through each transistor. Because IC1 is made equal to 10 IC2, and assuming TA = 25C, the previous equation becomes: VBE = 59 mV + 0.9 IC1 rBE (rBE ~ 0) As viewed on an oscilloscope, the change in VBE for a 10:1 change in IC is then displayed as shown in Figure 2 below: The output of the transdiode logarithmic converter comes from the idealized intrinsic transistor equation (for silicon): VBE = kT I In C q IS (1) Figure 2. where k = Boltzmann's Constant (1.38062 x 10 q = Unit Electron Charge (1.60219 x 10 -23 -19 With the oscilloscope ac coupled, the temperature dependent term becomes a dc offset and the trace represents the deviation from true log conformity. The bulk resistance can be calculated from the voltage deviation VO and the change in collector current (9 mA): J/K) C) T = Absolute Temperature, K (= C + 273.2) IS = Extrapolated Current for VBE0 IC = Collector Current rBE = An error term must be added to this equation to allow for the bulk resistance (rBE) of the transistor. Error due to the op amp input current is limited by use of the OP15 BiFET-input op amp. The resulting AMP01 input is: 1 V O x 9 mA 100 (3) This procedure finds rBE for Side A. Switching R1 and R2 will provide the rBE for Side B. Differential rBE is found by making R1 = R2. -6- REV. E MAT02 Figure 3. One-Quadrant Multiplier/Divider APPLICATIONS: NONLINEAR FUNCTIONS MULTIPLIER/DIVIDER CIRCUIT The excellent log conformity of the MAT02 over a very wide range of collector current makes it ideal for use in log-antilog circuits. Such nonlinear functions as multiplying, dividing, squaring and square-rooting are accurately and easily implemented with a log antilog circuit using two MAT02 pairs (see Figure 3). The transistor circuit accepts three input currents (I1, I2 and I3) and provides an output current IO according to IO = I1I2/I3. All four currents must be positive in the log antilog circuit, but negative input voltages can be easily accommodated by various offsetting techniques. Protective diodes across each base-to-emitter junction would normally be needed, but these diodes are built into the MAT02. External protection diodes are, therefore, not needed. For the circuit shown in Figure 3, the operational amplifiers make I1 = VX/R1, I2 = VY/R2, I3 = VZ/R3, and IO = VO/RO. The output voltage for this one-quadrant, log-antilog multiplier/ divider is ideally: VO = R3RO V XV Y (VX, VY, VZ > 0) R1R2 V Z (4) these effects can be lumped together as a total effective bulk resistance rBE. The rBEIC term causes departure from the desired logarithmic relationship. The rBE term for the MAT02 is less than 0.5 and rBE between the two sides is negligible. Returning to the multiplier/divider circuit of Figure 1 and using Equation (4): VBE1A + VBE2A - VBE2B - VBE1B + (I1 + I2 - IO - I3) rBE = 0 If the transistor pairs are held to the same temperature, then: II I I kT kT In 1 2 = In S1A S 2 A + (I1 + I2 - IO - I3) rBE (6) q I 3 IO q I S1B I S 2 B If all the terms on the right-hand side were zero, then In (I1 I2/I3 IO) would equal zero, which would lead directly to the desired result: IO = I S1A I S 2 A q + o = In I I (I + I2 - IO - I3) rBE kT 1 S1B S 2 B VO = VXVY/VZ Resistor values of 50 k to 100 k are recommended assuming an input range of 0.1 V to +10 V. I1I 2 =1+o I 3IO The base-to-emitter voltage of the MAT02 in its forward active operation is: The first term comes from the idealized intrinsic transistor equation previously discussed (see equation (1)). Extrinsic resistive terms and the early effect cause departure from the ideal logarithmic relationship. For small VCB, all of REV. E (8) For the MAT02, In (ISA/ISB) and ICrBE are very small. For small o, O ~ 1 + o and therefore: ERROR ANALYSIS kT I C In + rBEIC, VCB ~ 0 q IS (7) Note that this relationship is temperature independent. The right-hand side of Equation (6) is near zero and the output current IO will be approximately I1 I2/I3. To estimate error, define o as the right-hand side terms of Equation (6): If all the resistors (RO, R1, R2, R3) are made equal, then VBE = I1I 2 , where I1, I2, I3, IO > 0 I3 (9) (5) IO ~ I1I2 (1 - o) I3 The In (ISA/ISB) terms in o cause a fixed gain error of less than 0.6% from each pair when using the MAT02, and this gain error is easily trimmed out by varying RO. The IOUT terms are -7- MAT02 more troublesome because they vary with signal levels and are multiplied by absolute temperature. At 25C, kT/q is approximately 26 mV and the error due to an rBEIC term will be rBEIC/26 mV. Using an rBE of 0.4 for the MAT02 and assuming a collector current range of up to 200 A, then a peak error of 0.3% could be expected for an rBEIC error term when using the MAT02. Total error is dependent on the specific application configuration (multiply, divide, square, etc.) and the required dynamic range. An obvious way to reduce ICrBE error is to reduce the maximum collector current, but then op amp offsets and leakage currents become a limiting factor at low input levels. A design range of no greater than 10 A to 1 mA is generally recommended for most nonlinear function circuits. A powerful technique for reducing error due to ICrBE is shown in Figure 4. A small voltage equal to ICrBE is applied to the transistor base. For this circuit: RC r BE V and ICrBE = V VB = R2 1 R1 1 sumption or single-supply operation is needed. The value of frequency-compensating capacitor (CO) is dependent on the op amp frequency response and peak collector current. Typical values for CO range from 30 pF to 300 pF. Figure 4. Compensation of Bulk Resistance Error (10) FOUR-QUADRANT MULTIPLIER A simplified schematic for a four-quadrant log-antilog multiplier is shown in Figure 5. Similar to the previously discussed onequadrant multiplier, the circuit makes IO = I1 I2/I3. The two input currents, I1 and I2, are each offset in the positive direction. This positive offset is then subtracted out at the output stage. Assuming ideal op amps, the currents are: The error from rBEIC is cancelled if RC/R2 is made equal to rOUT R1. Since the MAT02 bulk resistance is approximately 0.39 , an RC of 3.9 and R2 of 10 R1 will give good error cancellation. In more complex circuits, such as the circuit in Figure 3, it may be inconvenient to apply a compensation voltage to each individual base. A better approach is to sum all compensation to the bases of Q1. The "A" side needs a base voltage of (VO/RO + VZ/ R3) rBE, and the "B" side needs a base voltage of (VX/R1+VY/R2) rBE. Linearity of better than 0.1% is readily achievable with this compensation technique. I1 = VX VR V V + ,I = Y + R R1 R2 2 R1 R2 (11) IO = Operational amplifier offsets are another source of error. In Figure 4, the input offset voltage and input bias current will cause an error in collector current of (VOS/R1) + IB. A low offset op amp, such as the OP07 with less than 75 V of VOS and IB of less than 3 nA, is recommended. The OP193, micropower op amp, should be considered if low power con- VX VY VR VO V + + + ,I = R R1 R1 R2 RO 3 R2 From IO = I1 I2/I3, the output voltage will be: VO = RO R2 V XV Y 2 VR R1 (12) Figure 5. Four-Quadrant Multiplier -8- REV. E MAT02 Figure 6. Multifunction Converter Collector current range is the key design decision. The inherently low rBE of the MAT02 allows the use of a relatively high collector current. For input scaling of 10 V full-scale and using a 10 V reference, we have a collector-current range for I1 and I2 of: -10 10 10 10 + + IC R2 R1 R1 R2 Linear error for this circuit is substantially improved by the small correction voltage applied to the base of Q1 as shown in Figure 5. Assuming an equal bulk emitter resistance for each MAT02 transistor, then the error is nulled if: (I1 + I2 - I3 - IO) rBE + VO = 0 The currents are known from the previous discussion, and the relationship needed is simply: V Z VO = VY V X m (15) VX, VY, and VZ are input voltages and the exponent "m" has a practical range of approximately 0.2 to 5. Inputs VX and VY are often taken from a fixed reference voltage. With a REF01 providing a precision 10 V to both VX and VY, the transfer function would simplify to: V Z VO = 10 10 m (16) As with the multiplier/divider circuits, assume that the transistor pairs have excellent matching and are at the same temperature. The In ISA/ISB will then be zero. In the circuit of Figure 6, the voltage drops across the base-emitter junctions of Q1 provide: kT I RB V = In Z RB + KR A A q IX (14) The output voltage is attenuated by a factor of rBE/RO and applied to the base of Q1 to cancel the summation of voltage drops due to rBEIC terms. This will make In (I1 I2/I3 IO) more nearly zero which will thereby make IO = I1 I2/I3 a more accurate relationship. Linearity of better than 0.1% is readily achievable with this circuit if the MAT02 pairs are carefully kept at the same temperature. REV. E The multifunction converter circuit provides an accurate means of squaring, square rooting, and raising ratios to arbitrary powers. The excellent log conformity of the MAT02 allows a wide range of exponents. The general transfer function is: (13) Practical values for R1 and R2 would range from 50 k to 100 k. Choosing an R1 of 82 k and R2 of 62 k provides a collector current range of approximately 39 A to 283 A. An RO of 108 k will then make the output scale factor 1/10 and VO = VXVY/10. The output, as well as both inputs, are scaled for 10 V full scale. r BE VO = V RO O MULTIFUNCTION CONVERTER (17) IZ is VZ/R1 and IX is VX/R1. Similarly, the relationship for Q2 is: kT I RB VA = In O q IY RB + (1 - K )RA (18) IO is VO/RO and IY is VY/R1. These equations for Q1 and Q2 can then be combined. I I RB + KR A In Z = In O I I RB + (1 - K )RA X Y -9- (19) MAT02 Substituting in the voltage relationships and simplifying leads to: m V Z RO VO = R V Y V , where X 1 (20) RB + KR A m = R + 1- K R ) A B ( The factor "K" is a potentiometer position and varies from zero to 1.0, so "m" ranges from RB/(RA + R B) to (R B + R A)/RB. Practical values are 125 for RB and 500 for RA; these values will provide an adjustment range of 0.2 to 5.0. A value of 100 k is recommended for the R1 resistors assuming a fullscale input range of 10 V. As with the one-quadrant multiplier/divider circuit previously discussed, the VX, VY, and VZ inputs must all be positive. The op amps should have the lowest possible input offsets. The OP07 is recommended for most applications, although such programmable micropower op amps as the OP193/OP293 offer advantages in low-power or single-supply circuits. The micropower op amps also have very low input bias-current drift, an important advantage in log/antilog circuits. External offset nulling may be needed, particularly for applications requiring a wide dynamic range. Frequency compensating capacitors, on the order of 50 pF, may be required for A2 and A3. Amplifier A1 is likely to need a larger capacitor, typically 0.0047 F, to assure stability. Figure 7. Fast Logarithmic Amplifier LOW-NOISE 1000 AMPLIFIER Accuracy is limited at the higher input levels by bulk emitter resistance, but this is much lower for the MAT02 than for other transistor pairs. Accuracy at the lower signal levels primarily depends on the op amp offsets. Accuracies of better than 1% are readily achievable with this circuit configuration and can be better than 0.1% over a limited operating range. The MAT02 noise voltage is exceptionally low, only 1 nV/Hz at 10 Hz when operated over a collector current range of 1 mA to 4 mA. A single-ended x1000 amplifier that takes advantage of this low MAT02 noise level is shown in Figure 8. In addition to low noise, the amplifier has very low drift and high CMRR. An OP184 is used for the second stage to obtain good speed with minimal power consumption. Small-signal bandwidth is 4.0 MHz, slew rate is 2.4 V/s, and total supply current is approximately 2.25 mA. FAST LOGARITHMIC AMPLIFIER The circuit of Figure 7 is a modification of a standard logarithmic amplifier configuration. Running the MAT02 at 2.5 mA per side (full-scale) allows a fast response with wide dynamic range. The circuit has a 7 decade current range, a 5 decade voltage range, and is capable of 2.5 s settling time to 1% with a 1 V to 10 V step. The output follows the equation: VO = R3 + R2 kT V REF In q R2 V IN (21) The output is inverted with respect to the input, and is nominally -1 V/decade using the component values indicated. Figure 8. Low-Noise, Single-Ended x 1000 Amplifier -10- REV. E MAT02 Transistors Q2 and Q3 form a 2 mA current source (0.65 V/ 330 ~ 2 mA). Each collector of Q1 operates at 1 mA. The OP184 inputs are 3 V below the positive supply voltage (RLIC ~ 3 V). Input stage gain is gmRL, which is approximately 100 when operating at IC of 1 mA with RL of 3 k. Since the OP184 has a minimum open-loop gain of 500,000, total open-loop gain for the composite amplifier is over 50 million. Even at closed-loop gain of 1000, the gain error due to finite open-loop gain will be negligible. The OP184 features excellent symmetry of slew-rate and very linear gain. Signal distortion is minimal. Input bias current is relatively low due to the high current gain of the MAT02. The minimum of 400 at 1 mA for the MAT02F implies an input bias current of approximately 2.5 A. This circuit should be used with signals having relatively low source impedance. A high source impedance will degrade offset and noise performance. This circuit configuration provides exceptionally low input noise voltage and low drift. Noise can be reduced even further by raising the collector currents from 1 mA to 3 mA, but power consumption is then increased. Dynamic range of this amplifier is excellent; the OP184 has an output voltage swing of 14.8 V with a 15 V supply. Input characteristics are outstanding. The MAT02F has offset voltage of less than 150 V at 25C and a maximum offset drift of 1 V/C. Nulling the offset will further reduce offset drift. This can be accomplished by slightly unbalancing the collector load resistors. This adjustment will reduce the drift to less than 0.1 V/C. REV.
