Abstract:
A photodetector receiver circuit, including: a photodetector for receiving an optical signal and converting the optical signal into a current; and a dynamic impedance circuit connected to the photodetector; wherein the dynamic impedance circuit is configured to have a first impedance during a charging phase and a second impedance during a discharging phase, the first impedance comprising a slower decay time than the second impedance.
