Abstract
A trigger sense circuit includes a pseudo-differential comparator circuit in signal communication with a pixel array. The pseudo-differential comparator circuit includes a first input in signal communication with a reference pixel group included in the pixel array to receive a pixel reference voltage, and a second input in signal communication with a target pixel group included in the pixel array to receive a pixel target voltage. The pseudo-differential comparator circuit is configured to selectively operate in a calibration mode to remove false trigger events and a comparison mode to detect at least one overheated pixel included in the target pixel group.
