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. A 32×32 element prototype sensor with 24-μm pixel pitch was fabricated in 1.2-μm CMOS and demonstrated
