Amplifier circuits and methods

摘要: Embodiments of the present invention provide an amplifier circuit and method that can be used to save power or reduce distortion in electronic system, such as a wireless communication system. In one embodiment, includes comprising transistor having gate terminal, drain body load. An input signal has different envelopes during time periods. A control coupled terminal is change voltage on when receives envelopes. Accordingly, biased use less lower are being received. Electronic systems, realize advantageous performance enhancements by utilizing other techniques employed embodiments invention.
