ABSTRACT:
Improved methods and systems for amplifying a signal are provided. Specifically, systems and methods for amplifying a signal through a lossy switch element tied to two or more voltage sources are provided. In the preferred embodiment, envelope information from the signal is used to smoothly transition between the two or more voltage sources to provide signal amplification over an increased range.
