Abstract
A method for balancing an electrical parameter (e.g, a current or a voltage) between phases in a multi-phase interleaved circuit includes sensing the electrical parameter, demultiplexing the electrical parameter in accordance with a phase-select signal, sampling the demultiplexed components into a plurality of digital signals, generating an error signal based on a difference between the digital signals, and modulating the phase-select signal, as applied to the phases, in accordance with the error signal.
