Abstract

Active pixel image sensing device that provides uniform integration periods and either independent pixel reset, row, pixel reset, or column pixel reset, having a plurality of photodetector elements arranged in a matrix of rows and columns, each of the photodetectors having a transfer gate operatively connecting the photodetectors to a floating diffusion and further including a reset and clamp and sample function. A reset transistor for each row of photodetectors having a gate that can have a predetermined voltage applied to reset each row, and a column reset transistor for each column of photodetectors having a gate that can have a predetermined voltage applied to reset each column. This allows for uniform integration periods and a signal sample and clamp circuit for the entire array of photodetectors.
