Linear CMOS image sensor for bio-microfluidic imaging system

A linear CMOS image sensor (CIS) with 16-stage time-delay integration (TDI) is proposed in this paper for bio-microfluidic imaging system. Compared to the traditional CIS for bio-microfluidic applications, this CIS achieves high speed and high sensitivity in low illumination condition, which is suitable for bio-microfluidic. Moreover, a simple voltage accumulator and 10-bit full-differential single-slope analog-to-digital converter (ADC) are deployed for high-speed and low-noise readout.
