A 96×96 1V ultra-low power CMOS image sensor for biomedical application

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.

“…The most common CMOS pixel sensor is the active pixel sensor (APS) [6,[13][14][15][16][17][18][19][20][21][22][23][24][25] which has 2 conventional types, namely 3T APS [6,14,18,[21][22][23][24] and 4T APS [13][14][15][16][17][18][19][20]25], as shown in Fig. 3.…”

“…In particular, 2 types of pixel structure are reviewed. They are active pixel sensor (APS) [6,[13][14][15][16][17][18][19][20][21][22][23][24][25] in Section 2 and pseudo-active pixel sensor (PAPS) [26,27] in Section 3. Then a new sensor called zero bias pixel sensor (ZBPS), that can eliminate dark current, is proposed in Section 4.…”

“…The recent advance of microfluidics-based LOC technology has introduced the possibility for the miniaturized microflow cytometer for potable flow cytometry [131-133, 136, 137]. With the integration of CMOS image sensor chip underneath the microfluidic channel, microfluidics-based lensless imaging systems [44,55,57,61,63,64,73,138] can be developed for portable contact-imaging [43] based microflow cytometer. Illuminated by incoherent light source, the direct projected shadow or contact images of cells can be captured by the image sensor underneath without lenses [44,55,57,61,63,64,138].…”
