摘要

Abstract: The design of a low-light-level CMOS active-pixel-sensor (APS) with on-chip, semi-parallel analog-to- digital (A/D) conversion is presented. The imager consists of a 128 $MUL 128 array of active pixels at a 50 $mu@m pitch. Each column of pixels shares a 10-bit A/D converter based on first-order oversampled sigma-delta ($Sigma@-$Delta@) modulation. The 10-bit outputs of each converter are multiplexed and read out through a single set of outputs. A semi-parallel architecture is chosen to achieve 30 frames/second operation even at low light levels. The sensor is designed for less than 10 e$+$MIN$/ rms noise performance. A 28 $MUL 28 active-pixel-sensor (APS) with 40 $MUL 40 $mu@m$+2$/ pixels as well as individual elements of the sigma-delta modulator have been fabricated and tested using MOSIS* 2 $mu@m CMOS technology.!8
