Patent ID: 7579819

Claim:
A regulator circuit, comprising: a comparator circuit including a first input that is coupled to a first node, a second input that is coupled to a second node, and an output, wherein the comparator is arranged to provide a comparison output signal at the output of the comparator based, in part, on a comparison of a feedback signal at the first node with a modified reference signal at the second node; an impedance circuit that is arranged to couple a reference signal to the second node such that the modified reference signal is based, in part, on the reference signal; a switch that is coupled between a current sense node and another node; and a capacitor circuit that is coupled between said another node and the second node, wherein the capacitor is arranged to AC-couple a current sense voltage at the current sense node to the second node such that the modified reference signal is based, in part, on the current sense voltage.
