A 128-Stage Analog Accumulator for CMOS TDI Image Sensor

The impacts of parasitic phenomenon on the performance of the analog accumulator in CMOS TDI image sensor are analyzed in this paper, and a modified accumulator with decoupling capacitor Cd to combat the parasitic phenomenon is also proposed. A 128-stage modified accumulator is designed and simulate...
