Abstract
A regulator circuit includes a multiphase ramp generator circuit, an amplifier circuit configured to receive a plurality of phase sense signals and provide a plurality of respective error signals, and an adder circuit configured to receive the error signals and ramp generator signals. The ramp generator signals are received from the multiphase ramp generator circuit and the adder circuit is configured to provide a plurality of respective adjusted ramp generator signals. The regulator can be a multiphase switching regulator circuit.
