Abstract
An amplification system is provided that comprises a push-pull amplifier system having a first power transistor series coupled with a second power transistor that alternately switch between a push-pull amplifier mode of operation and a single-ended amplifier mode of operation. In the push-pull amplifier mode, both the first power transistor and the second power transistor alternately conduct to provide an amplified output signal to an output load in response to an input signal having an amplitude that is greater than or equal to a threshold level. In the single-ended amplifier mode of operation, the first power transistor conducts and the second power transistor is disabled for amplification purposes in response to the input signal having an amplitude that is less than the threshold level.
