Column-wise clamp voltage driver for suppression of noise in an imager |
摘要 |
An imager having column-wise clamp voltage drivers. Each clamp voltage driver is substantially identical to the output circuitry of the imager's pixels in that column and is designed to track the noise experienced by the readout pixels. Each clamp voltage driver generates and drives the appropriate clamp voltage to store reset and pixel signals in associated column sample and hold circuitry while suppressing the noise typically experienced during the readout process.
