The power amplifier (PA) consumes more electrical power than any other block in a cellular basestation and is a significant factor
in the operating expense for the service provider. Since complex digital modulation requires extremely high linearity from the PA,
it must be driven well below saturation where it is most efficient. To improve PA efficiency, designers use digital techniques
