Linear Current-Mode Active Pixel Sensor

IEEE Journal of Solid-State Circuits, 2007
A current mode CMOS active pixel sensor (APS) providing linear light-to-current conversion with inherently low fixed pattern noise (FPN) is presented. The pixel features adjustable-gain current output using a pMOS readout transistor in the linear region of operation. This paper discusses the pixel's design and operation, and presents an analysis of the

Frame-transfer CMOS active pixel sensor with pixel binning

IEEE Transactions on Electron Devices, 1997
The first frame-transfer CMOS active pixel sensor (APS) is reported. The sensor architecture integrates an array of active pixels with an array of passive memory cells. Charge integration amplifer-based readout of the memory cells permits binning of pixels for variable resolution imaging.
