Abstract: A receiver for a light detection and range finding system is disclosed. The receiver can include an optoelectrical device to receive a pulse of light reflected from a target and to convert the pulse of light to a current pulse. The receiver can also include a transimpedance amplifier (TIA) to convert the current pulse to a voltage pulse. The receiver can also include a tunable filter that has an input coupled to an output of the TIA. The tunable filter can have a frequency response that is adjustable. The TIA and the tunable filter can be disposed on a single integrated circuit (IC) die.
