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 amplifier-based readout of the memory cells permits binning of pixels for variable resolution imaging. A 32 2 32 element prototype sensor with 24-m pixel pitch was fabricated in 1.2-m CMOS and demonstrated.
