Abstract: A complementary metal-oxide-semiconductor sensor array includes an active sensing area of pixels arranged in an array with a pitch, each pixel including an exposed surface electrode alongside switches and logic gates, and non-overlapping clocks configured to rapidly charge and discharge the exposed surface electrode, wherein control signals steer a switched output current between shared column outputs.
