Abstract

Centering pulses within the output sample period corrects for instantaneous phase errors in multi-reference switching amplifiers. In the preferred embodiment, the pulses are ordered by the relative magnitude of each switched reference.

Claims (5)

1. In a multi-reference switching amplifier generating a plurality of output pulses, a modulation technique comprising the steps of:

providing a plurality of switching devices connected to multiple voltages on both sides of a load; and

centering the pulses delivered to the switching devices within an output sample period.

2. The method of claim 1 , further including the step of:

ordering the pulses by the relative magnitude of each switched reference.
