Using offset cancellation circuit to mitigate beat-frequency oscillation of phase currents in a multiphase interleaved voltage regulator |
摘要 |
For a multiphase interleaved voltage regulator, an offset cancellation circuit is applied for each phase separately. The current loop gain of each phase is thus increased to mitigate the beat-frequency oscillation in phase currents when the beat frequency is below the bandwidth of the low-pass filter in the offset cancellation circuit, without introducing additional instability issue that is the drawback of increasing current-sensing gain.
