Abstract
An optical receiver suitable for connecting to a photodiode generating a photocurrent with a sensing resistor and a diode circuit in parallel with the sensing resistor to limit the voltage across the sensing resistor. The diode circuit allows for a larger resistor providing greater sensitivity without risking violating the necessary headroom available to the photodiode.
