Abstract
A circuit for diminishing mismatch effects between at least two switched signals includes at least three processing circuits configured to receive at least two switched signals such that each of the switched signals is associated with one of the processing circuits leaving at least one unassociated processing circuit. A controller circuit is configured to switch one of the switched signals to be associated with one of the unassociated processing circuit(s) upon at least one specified interval such as, for example, at a transition of the switched signal. The circuit may be incorporated into an audio amplifier configured to provide information carried on the switched signals to one or more speakers that provide an audio output. A one-processor circuit approach includes switching frames of a switched signal between positive and negative inputs of a processor circuit to average out errors introduced by the processor circuit.
