Abstract :
An ultra-low power CMOS image sensor is designed for endomicroscope applications. The chip will be fabricated through Global Foundries 0.18μm standard CMOS process with 1V power supply. The total power consumption is 6μW for 96×96 array with 5fps frame rate, where global amplifier consumes 3.3 μW, 10-bit SAR ADC consumes 900nW at 50kS/s, and on-chip digital processing further reduces IO power consumption down to 1.6μW.
