Abstract
In one example, a circuit includes a voltage source, a pass module, a differential amplifier module, and a control module. The pass module is configured to electronically couple, using a channel having a resistance, the voltage source and a load and to modify the resistance of the channel based on a control signal. The differential amplifier module is configured to generate a differential signal based on a comparison of a voltage reference and a representation of a voltage at the load. The control signal is based on the differential signal. The control module is configured to generate the representation of the voltage at the load according to a transfer function. The transfer function includes a zero positioned substantially at a crossover frequency of the transfer function.
