PI3034A 200DPI Sensor Chip Engineering Data Sheet
Peripheral Imaging Corporation PI3034A sensor chip inch resolution linear array image sensor chip, which uses PIC's proprietary CMOS Image Sensing Technology. This image sensor's intended applications fabricate Contact Image Sensor, modules with various lengths. This accomplished mounting them printed circuit board (PCB) through end-to-end butting process. This process generally referred chip-on-board technology. typical circuit implementation size 1728 elements module shown schematic diagram page schematic demonstrates operational implementation interfacing circuits. They used facsimile, scanner, check reader, office automation equipment. Figure block diagram sensor chip. Each sensor chip consists detector elements, their associated multiplexing switches, buffers, chip selector. detector element-to-element spacing approximately size each chip without scribe lines 7950 Each sensor chip bonding pads. symbols functions described Table

Notes: Tint stands line scanning rate integration time. determined time interval between start pulses. stands input clock frequency: total active line scan time module 3.45 line integration time. average pixel amplitudes complete line scan. These video pixels converted from signal currents produced phototransistor each pixel site. signal current charges video line capacitance that isolated with amplifier buffer. output current proportional charges that have been collected phototransistor's base through photon-to-electron conversion process. These charges base draw signal current through emitter proportionally Beta phototransistor. Then emitter current flows onto output video line capacitance where integrated converted signal voltage. This signal voltage that host receiver senses. Before accessing subsequent pixel, this video signal video line capacitance reset through shunt switch video line. Then next pixel sequence readout onto video line. This video buffer amplifier terminating video line provides necessary amplification. Most user generally their operating output signal peak average with saturation level circuit reference attached schematic diagram page Typical amplification (adjustable) gain between times voltage that measured video line.
