International Classification:
H03F 3/08
US Classification:
250214A, 2502141, 327514
Abstract:
A method and apparatus is provided for biasing an avalanche photodiodes (APD). The method includes developing a first output signal s(v) from the APD when biased with a first bias voltage vand developing a second output signal s(v) from the APD when biased with a second bias voltage v, wherein s(v)=PRZM(v), (P) is an light power illuminating the APD, R is a responsivity of the APD, M(v) is an APD avalanche gain and Z is a trans-impedance amplifier gain (Z). The method continues by acquiring a ratio r=s(v)/s(v)=PRZM(v)/[PRZM(v)]=M(v)/M(v) and invoking a feedback control method to bias the APD using the ratio r.
