Abstract
Example embodiments relate to light detectors for nearby object detection in light detection and ranging (lidar) devices. An example embodiment includes a lidar device. The lidar device includes a light emitter configured to emit a light signal at a first time. The lidar device also includes a light detector configured to detect the emitted light signal. Additionally, the lidar device includes a biasing circuit configured to modify a detector bias using a bias signal. The bias signal ramps the detector bias from a first bias level at the first time to a second bias level at a second time. The second time is separated from the first time by a ramp duration. The ramp duration is sufficient to prevent any internal feedback within the lidar device caused by the emitted light signal from saturating the light detector or detection circuitry associated with the light detector.
