US Patent 9069060 Circuit architecture for optical receiver with increased dynamic range

A circuit architecture for a sensing component of a Light Detection and Ranging (LIDAR) device can provide a wide dynamic range. The circuit architecture includes at least one photosensor, each photosensor including an input that is configured to receive an optical signal; a respective diode corresponding to each photosensor, each respective diode including an input that is coupled to an output of the corresponding photosensor; a multiplexer including an input that is coupled to the output of each of the at least one photosensors; and an amplifier including an input that is coupled to the output of the multiplexer.
