Dynamic control of diode bias voltage (photon-caused avalanche)
Methods and devices are provided for determining an operating bias voltage of a photodiode. One example method includes (i) varying a bias voltage of a photodiode; (ii) detecting spurious signals generated by the photodiode while varying the bias voltage of the photodiode; (iii) determining a threshold bias voltage at which a frequency of occurrence of the spurious signals reaches a threshold frequency; (iv) determining an operating bias voltage for the photodiode based on at least the threshold bias voltage; and (v) operating the photodiode with the operating bias voltage in a light-detection and ranging (LIDAR) system.
