Patent ID: 6952093

Claim:
An apparatus for adjusting small-signal compensation in a switching regulator that includes an inductor and a switching circuit that is arranged to provide selective charging of the inductor, the apparatus comprising: a measurement circuit that is arranged to provide a measurement signal (V 1 ) that in associated with operating conditions for the inductor; a feedback circuit that is arranged to provide a feedback signal in response to an output signal that is associated with the switching regulator; a control circuit that is arranged to provide a drive signal to the switching circuit to effect selective charging of the inductor, wherein the feedback circuit and the control circuit are arranged in a feedback loop of the switching regulator such that the switching regulator has a loop transfer function with a second-order pole and a zero, wherein a location associated with the zero is dynamically adjusted by at least one of the feedback circuit and the control circuit in response to the measurement signal to counteract the effect of the second-order pole on stability of the switching regulator.
