Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A method for operating a voltage regulator, comprising:
providing a reference signal pathway regulation signal and a first switching clocking signal to a reference channel;
providing, by the reference channel, a first charging signal to a first energy storage element to contribute to an output signal;
providing a regulator signal pathway regulation signal and a second switching clocking signal to a regulator channel, wherein the second switching clocking signal is offset in phase from the first switching clocking signal;
providing, by the regulator channel, a second charging signal to a second energy storage element to contribute to the output signal;
comparing, by a global error circuit, the output signal with a reference input signal to generate a global error signal;
providing the global error signal and a reference signal pathway error signal to a combination circuit coupled to the global error circuit and the reference channel;
generating, by the combination circuit, the reference signal pathway regulation signal; and
comparing, by a local error circuit, the first charging signal prior to being received by the first energy storage element with the second charging signal prior to being received by the second energy storage element to generate a local error signal to contribute to a correction of the second charging signal.
