Abstract
Systems and methods are provided herein for improved short range object detection in LIDAR systems. An example method may include providing, by a biasing voltage source, a first biasing voltage to a photodetector of a LIDAR system at a first time corresponding to a light emission from an emitter of the LIDAR system. The example method may also include providing, by the biasing voltage source, a second biasing voltage to the photodetector at a second time subsequent to the first time. The example method may also include receiving, by a pole/zero cancellation subcircuit of the LIDAR system, a first output signal from the photodetector. The example method may also include removing, by the pole/zero cancellation subcircuit, an undershoot or overshoot from the first output signal. The example method may also include receiving, by a first gain subcircuit, a second output signal from the pole/zero cancellation subcircuit.
