Abstract
A method and attendant circuitry reduces the number of regulatory and switching devices in a multi-reference switching amplifier. In the preferred embodiment, multiple independently-modulated effective references are summed at a load through use of both linear and switched control of switching devices.
Claims5
In a multi-reference switching amplifier of the type wherein switching devices control power supplied to a load in response to an input data stream having a sign, a simplified output topology, comprising:
- a plurality of effective references;
- and
- circuitry for summing the references at the load through linear and switched control of the switching devices.
