Patent ID: 7155133

Claim:
An optoelectronic assembly, selected from one of an optoelectronic transceiver and an optoelectronic receiver, comprising: a housing; an avalanche photodiode disposed within the housing; a power supply disposed within the housing to supply a reverse-bias voltage to the avalanche photodiode, wherein the power supply comprises: a switch controller that drives a transistor; and a feedback loop including a resistor divider network connected with the switch controller; a current mirror connected with the power supply to mirror a current in the avalanche photodiode, the mirrored current flowing through a sense resistor, the voltage across the sense resistor being proportional to the current in the avalanche photodiode; and an integrated circuit disposed within the housing, wherein the integrated circuit stores at least one digital value associated with the avalanche photodiode for controlling the reverse-bias voltage supplied to the avalanche photodiode, the at least one digital value including the data describing the temperature of the avalanche photodiode, wherein the integrated circuit connects with the resistor divider network of the feedback loop to use the at least one digital value to adjust a duty cycle of the transistor in order to adjust the reverse-bias voltage supplied to the avalanche photodiode by the power supply.
