An enhanced-performance CMOS imager with a flushed-reset photodiode pixel.

An enhanced-performance CMOS imager with a flushed-reset photodiode pixel.

A new front-end for photodiode-based CMOS imagers is presented. Degradation in imaging performance due to conventional hard- and soft-reset of pixels is analyzed. To overcome these limitations, the design and operation of a flushed-reset pixel is described. The flushed-reset pixel combines the best...
