Patent ID: 8482346

Claim:
A high efficiency amplifier system comprising: a first output stage included as part of an integrated circuit and configured to output a first amplified signal amplified by the first output stage; a second output stage included as part of the integrated circuit and coupled in parallel with the first output stage, the second output stage configured to output a second amplified signal amplified by the second output stage; and a pulse width modulator operable to control a plurality of switches included in the first and second output stages with interleaved switching, the pulse width modulator further operable to balance an output power of each of the first and second output stages based on a signal indicative of a current output from each of the first and second output stages; where the pulse width modulator is further operable to disregard the respective current output from each of the first output stage and the second output stage in response to a respective switching event in each of the first output stage and the second output stage.
