A Light-detection and ranging (LIDAR) system for controlling a bias voltage is provided. The LIDAR system includes a light source configured to emit light pulses and a light sensor configured to receive light pulses transmitted by the light source and scattered by an object. A voltage source is provided to apply the bias voltage to the light sensor. The LIDAR system further includes a sensor configured to generate a signal indicative of a temperature of the light sensor. The LIDAR system includes a controller communicably coupled to the light source, the light sensor, the voltage source and the sensor. The controller is configured to receive the signal indicative of the temperature of the light sensor. Further, the controller is configured to measure the bias voltage currently applied to the light sensor. The voltage source is regulated based at least on the temperature of the photodiode and the measured bias voltage currently applied to the light sensor.
