21. A sensor circuit comprising:
a transmitter circuit;
a first receiver circuit; and
a second receiver circuit,
wherein the transmitter circuit is operable to receive an enable signal from the first receiver circuit and drive an emitter to emit a first optical signal based on one or more control signals received from the first receiver circuit,
wherein the first receiver circuit is configured to obtain a detection signal corresponding to a return signal from an object and send time of flight data to a master controller, and
wherein the second receiver circuit is configured to extend near field detection.
