KLI-2113 Linear CCD Image Sensor Description The KLI-2113 Image Sensor is a high dynamic range, multispectral, linear CCD image sensor ideally suited for demanding color scanner applications. The imager consists of three parallel 2098-element photodiode arrays - one for each primary color. The KLI-2113 sensor offers high sensitivity, a high data rate, low noise, and negligible lag. Independent exposure control for each channel allows color balancing at the front end. CMOS-compatible 5 V clocks, and single 12 V DC supply are all that are required to drive the KLI-2113 sensor, simplifying the design of interface electronics. www.onsemi.com Table 1.

Single Channel Schematic Pixel Summing The effective resolution of this sensor can be varied by enabling the pixel summing feature. A separate pin is provided for the last shift register gate labeled f2s. This gate, when clocked appropriately, stores the summation of signal from adjacent pixels. This combined charge packet is then transferred onto the sense node. As an example, the sensor can be operated in 2-pixel summing mode (1,049 pixels), by supplying a f2s clock which is a 75% duty cycle signal at 1/2 the frequency of the f2 signal, and modifying the fR clock as depicted in Figure 10. Applications that require full resolution mode (2,098 pixels), must tie the f2s pin to the f2 pin. Refer to Figure 9 and Figure 10 for additional details. Exposure Control Exposure control is implemented by selectively clocking the LOG gates during portions of the scanning line time. By applying a large enough positive bias to the LOG gate, the channel potential is increased to a level beyond the `pinning level' of the photodiode. (The `pinning' level is the maximum channel potential that the photodiode can achieve and is fixed by the doping levels of the structure.) With TG1 in an `off' state and LOG strongly biased, all of the photocurrent will be drawn off to the LS drain. Referring to Figure 9, one notes that the exposure can be controlled by pulsing the LOG gate to a `high' level while TG1 is turning `off' and then returning the LOG gate to a `low' bias level sometime during the line scan. The effective exposure (tEXP) is the net time between the falling edge of the LOG gate and the falling edge of the TG1 gate (end of the line). Separate LOG connections for each channel are provided, enabling on-chip light source and image spectral color balancing. As a cautionary note, the switching transients of the LOG gates during line readout may inject an artifact at the sensor output. Rising edge artifacts can be avoided by switching LOG during the photodiode-to-CCD transfer period, preferably, during the TG1 falling edge. Depending on clocking speeds, the falling edge of the LOG should be synchronous with the f1/f2 shift register readout clocks. For very fast applications, the falling edge of the LOG gate may be limited by on-chip RC delays across the array. In this case, artifacts may extend across one or more pixels. Correlated double sampling (CDS) processing of the output waveform can remove the first order magnitude of such artifacts. In high dynamic range applications, it may be advisable to limit the LOG fall times to minimize the current transients in the device substrate and limit the magnitude of the artifact to an acceptable level. Image Acquisition During the integration period, an image is obtained by gathering electrons generated by photons incident upon the photodiodes. The charge collected in the photodiode array is a linear function of the local exposure. The charge is stored in the photodiode itself and is isolated from the CCD shift registers during the integration period by the transfer gates TG1 and TG2, which are held at barrier potentials. At the end of the integration period, the CCD register clocking is stopped with the f1 and f2 gates being held in a `high' and `low' state respectively. Next, the TG gates are turned `on' causing the charge to drain from the photo-diode into the TG1 storage region. As TG1 is turned back `off', charge is transferred through TG2 and into the f1 storage region. The TG2 gate is then turned `off', isolating the shift registers from the accumulation region once again. Complementary clocking of the f1 and f2 phases now resumes for readout of the current line of data while the next line of data is integrated. www.onsemi.com 3 KLI-2113 Charge Transport a parallel format at the falling edge of the f2s clock. Resettable floating diffusions are used for the charge to voltage conversion while source followers provide buffering to external connections. The potential change on the floating diffusion is dependent on the amount of signal charge and is given by DVFD = DQ / CFD, where DVFD is the change in potential on the floating diffusion, DQ is the amount of charge, and CFD is the capacitance of the floating diffusion node. Prior to each pixel output, the floating diffusion is returned to the RD level by the reset clock, fR. Readout of the signal charge is accomplished by two-phase, complementary clocking of the Phase 1 and Phase 2 gates (f1 and f2) in the horizontal (output) shift register. The register architecture has been designed for high speed clocking with minimal transport and output signal degradation, while still maintaining low (4.75 VP-P min) clock swings for reduced power dissipation, lower clock noise and simpler driver design. The data in all registers is clocked simultaneously toward the output structures. The signal is then transferred to the output structures in www.onsemi.com 4 KLI-2113 Physical Description Pin Description and Device Orientation VIDR 1 28 VIDG SUB 2 27 SUB RD 3 26 VDD fR 4 25 VIDB LOGR 5 24 SUB LOGG 6 23 N/C SUB 7 22 LOGB N/C 8 21 N/C LS 9 20 N/C IG 10 19 ID TG2 11 18 TG1 N/C 12 17 N/C f2s 13 16 N/C f2 14 15 f1 Figure 3.
