A Capacitance-Compensation Technique for Improved Linearity in CMOS Class-AB Power Amplifiers
... To meet the simultaneous requirements of high linearity and reasonable efficiency, power amplifiers in nonconstant-envelope systems are often operated in a class-AB mode; the linearity can be superior to that in class-B or higher operation and the efficiency is superior to that in class-A operation. ...

Buck converter
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
