A CMOS active pixel sensor that achieves wide intrascene dynamic range using dual sampling is reported. A 64 × 64 element prototype sensor with dual output architecture was fabricated using a 1.2-μm n-well CMOS process with 20.4-μm pitch photodiode-type active pixels. The sensor achieves an intrascene dynamic range of 109 dB without nonlinear companding.
