– 3 –1. OUTLINE OF CIRCUIT DESCRIPTION1-1. CMOS CIRCUIT DESCRIPTION1. IC ConfigurationThe CMOS peripheral circuit block basically consists of thefollowing ICs.IC911 (MT9F001I12STCV)CMOS imagerCDS, AGC, ADC built-inH driver, V driver, serial communication circuit built-in2. IC911 (CMOS)[Structure]The electric charges which are generated when each pixel isoptically converted are in turn converted into signal voltagesby the FD amplifier, and they are then transmitted by the built-in H driver and V driver. The signals are sampled and ampli-fied by the CDS and PGA circuits at the point they are output,and then they are AD converted and output. The output usesthe 12 bit LVDS interface.1/2.3-inch positive pixel array CMOS-type fixed imaging ele-mentEffective pixels 4384 (H) X 3288 (V)
