Abstract
A pixel cell includes a latch having an input terminal and an output terminal. The latch is coupled to provide a latched output signal at the output terminal responsive to the input terminal. A first precharge circuit is coupled to precharge the input terminal of the latch to a first level during a reset of the pixel cell. A single photon avalanche photodiode (SPAD) is coupled to provide a SPAD signal to the input terminal of the latch in response to a detection of a photon incident on the SPAD.
