Abstract
Biasing methods and devices for power amplifiers are described. The described methods and devices use the power amplifier output voltage to generate bias voltages. The bias voltages are obtained using rectifiers and voltage dividers. The described biasing methods and devices can be used with class-E power amplifiers.
