Abstract
Exemplary techniques for implementing an amplifier suitable for RF amplification, such as a tuned class DE amplifier, are disclosed. One disclosed embodiment of a circuit for amplifying an RF signal includes a push-pull amplifier comprising a push transistor and a pull transistor. A first driver amplifier drives the push transistor of the push-pull amplifier with a first RF signal. A second driver amplifier drives the pull transistor of the push-pull amplifier with a second RF signal different from the first RF signal.
