Abstract
A bias circuit () of an avalanche photodiode, APD, comprising: a voltage conversion module () connected to the APD, wherein the voltage conversion module () is configured to convert an input supply voltage (Vin) to a bias voltage for the APD; an error amplifier () connected to the voltage conversion module () for implementing a feedback control; a voltage feedback loop () configured to provide the error amplifier () a first analog signal related to the bias voltage; and a current feedback loop () configured to provide the error amplifier () a second analog signal related to the APD current; wherein the error amplifier () is configured to control the voltage conversion module () based on the first and the second analog signals.
