Maximum output power amplifier of a majority of devices with limited power reduction capability

摘要

A first amplifier (28) is configured for accepting a signal input and providing a drive signal to a load. A second amplifier (42) is configured in a voltage follower configuration with an input signal derived from the output (30) of the first amplifier. The output terminal (44) of the second amplifier (42) is coupled in parallel with the first output terminal (30) to the load. The output signal from the second amplifier (42) is nearly an exact duplicate of the output signal from the first amplifier (28) and the output signal contributions from the two amplifiers are substantially equal.
