Abstract
To reduce power consumption in a CMOS imager readout path, we use partial settling of the column values into a SAR-ADC, creating a 320H×240V prototype sensor with two column-shared 10-bit ADCs, which consumes 2.2mW at 130 fps. The measured INL and DNL with a third order correction of partial settling behavior is +1.855LSB/-1.855LSB and +0.337LSB/-0.179LSB, respectively. The input referred readout noise is 5e- with a conversion gain of 90uV/e-.
