Abstract
A circuit for providing temperature compensation to sense signals in a single-ended DC resistance (DCR) sensing network for a multiphase switching power supply includes a temperature compensation calculator circuit generating a compensation adjust signal indicative of a sensed temperature; a compensating impedance network receiving the positive sense signals for all the phases and generating a correction signal for each phase in response to at least the positive sense signal for each phase and the compensation adjust signal; an average circuit coupled to average the correction signals of all phases, where copies of the average correction signal are applied to modify the positive sense signals; and an amplifier circuit receiving a summed positive sense signal being the sum of the modified positive sense signals for all the phases and a summed negative sense signal to generate an output signal having substantially zero temperature coefficient over the first frequency range.
