All-CMOS Compressive Sensing for Biological Imaging

An apparatus includes an array of pixels. At least a first pixel in the array of pixels includes a first detector to generate a first electrical signal in response to irradiation by incident radiation, a first transistor electrically coupled to the first detector, and at least one logic gate to implement a Boolean AND logic function. The logic gate includes a first input terminal to receive a first exposure signal, a second input terminal to receive a first reset signal, and an output terminal, electrically coupled to the first transistor, to output to the first transistor a first control signal to variably control a first variable exposure time of the first detector and to reset the first detector.
