Abstract
An imaging device includes a focal plane array of demodulation pixel cells. Each of the demodulation pixel cells includes a pinned photodiode, demodulation gates operable to demodulate optical signals sensed by the pinned photodiode and to transfer accumulated photo-charges to a respective one of a multitude of sense nodes, a readout circuit operable selectively to read out signals from the sense nodes, and a background light suppression circuit including cross-coupled current mirrors.
