Abstract
Disclosed herein is an improved power amplifier, referred to as a Switched-Capacitor Radio Frequency Power Amplification (SCPA). The SCPA may be fabricated with scale CMOS technology. The SCPA may include a plurality of stages, each stage including a storage device, a switch, and selection circuitry. Various combinations of the stages may produce an output signal based on characteristics of a reference signal to be amplified. The output from the stages may be combined to create an amplified approximate square wave. The amplified square wave may be filtered by output circuitry such as a bandpass matching circuit, resulting in an output signal that may be an amplified version of the reference signal.
