Abstract
A circuit sets an output potential at a radio frequency (RF) output of a pin photoreceiver that includes an ohmic terminal resistor connected between a supply voltage and the RF output. The circuit includes a control loop with an ohmic replication resistor having a resistance approximately equal to a resistance of the ohmic terminal resistor. The control loop further includes a sub-circuit configured to measure a voltage difference across the ohmic replication resistor and to reproduce the voltage difference as the supply voltage at an output terminal of the control loop.
