Patent ID: 7643322

Claim:
A circuit for regulating an output signal, comprising: a regulator controller, including: a signal adjustment circuit that is arranged to receive a first sense signal that is based, at least in part, on the output signal during a steady state of operation; to receive a reference signal; and to provide an adjusted signal by adjusting the reference signal, wherein the adjustment is based on a value of the first sense signal at a first time and a value of the first sense signal at a second time; a comparison circuit that is arranged to receive the adjusted signal and a second sense signal that is based, at least in part, on the output signal, and is further arranged to provide a comparison signal by performing a comparison between the adjusted signal and the second sense signal; and a control circuit, including: a one shot circuit that is arranged to receive the comparison signal and to provide a switch control signal, and is arranged such that if the comparison signal is asserted, the control signal is asserted for a configured duration and is de-asserted at the end of the configured duration.
