Abstract
A pixel output processing circuit of a focal plane array (FPA) having a plurality of laser range finding pixels (LRF) is provided. The respective LRF pixels output a high frequency analog signal in response to sensing a reflected laser pulse. The pixel output processing circuit includes a common net and a detection circuit. The common net is connected to a amplifying transistor of each of the LRF pixels for receiving analog signals output from the respective LRF pixels. The detection circuit is coupled to the common net and outputs a pulse flag in response to detecting that a high frequency analog signal has been received by the common net.
