As a result of inefficiency, radio frequency (RF) power amplifiers typically consume high levels of current. Consequently, there have been numerous attempts to use external circuitry in order to improve the efficiency of RF power amplifiers located on integrated circuits (ICs); however, these attempts have failed to provide the desired improvements...

In many electronics applications various blocks of components on the integrated circuit may have optimal power consumption at different operational voltages. Power optimization and low power requirements are getting even more critical in wireless applications. Several low power schemes are in use today. In some mobile applications, minimizing power...
