Abstract
A circuit includes a reference signal generating part configured to generate a plurality of reference signals having levels different from each other, a comparing part configured to compare a ripple signal with the reference signals to determine a level of the ripple signal, a compensating signal generating part configured to generate a compensation ripple signal corresponding to the level of the ripple signal, where the compensation ripple signal has a phase opposite to the ripple signal, and a push-pull circuit configured to stabilize the compensation ripple signal.
