These light modulation photo ICs were developed for optical synchronous detection under disturbance background light.

A photodiode, preamplifier, comparator, oscillator, LED driver and signal processing circuit, etc. are all integrated on

a monolithic photo IC chip. Optical synchronous type photoreflectors and photointerrupters, which less susceptible to

disturbance background light, can be easily conﬁ gured by just connecting an external LED to this photo IC. Our unique

circuit design achieves an allowable background light level of 10000 lx typ. (S4282-51, S6986, S10053) and a minimum

detection level of 0.2 W/mm2 typ. (S6809, S6846, S7136/-10).

Block diagram and internal functions

(a) Oscillator and timing signal generator

The oscillator produces a reference oscillation output by charging and discharging the built-in capacitor with constant current. The

oscillation output is fed to the timing signal generator, which then creates LED drive pulses and various timing pulses for digital sig-

nal processing.

(b) LED driver circuit

This circuit drives an external LED using the LED drive pulses created by the timing signal generator. The duty cycle is 1/16.

The photodiode is formed on the same monolithic chip. A photocurrent generated in the photodiode is converted to a voltage by

a preampliﬁ er circuit. The preampliﬁ er circuit uses an AC ampliﬁ er to expand the dynamic range versus DC or low-frequency back-

ground light, without impairing signal detection sensitivity.

(d) Capacitive coupling, buffer ampliﬁ er and reference voltage generator

Capacitive coupling removes low-frequency noise and also cancels the DC offset in the preampliﬁ er. The buffer ampliﬁ er boosts the

signal up to the comparator level, and the reference voltage generator produces a comparator level voltage.

(e) Comparator circuit

The comparator circuit has a hysteresis function to prevent chattering caused by small ﬂ uctuations in the input light.

(f) Signal processing circuit

The signal processing circuit consists of a gate circuit and digital integrator circuit. The gate circuit discriminates input pulses during

synchronous detection, to prevent operational errors caused by asynchronous background light. Background light which is synchro-

nized with the signal detection timing cannot be eliminated by the gate circuit, but is canceled out by the digital integrator circuit at

the latter stage.

(g) Output circuit

This circuit serves as an output buffer for the signal processing circuit and outputs the signal to an external circuit.
