A CMOS RF Power Amplifier with Parallel Amplification for Efficient Power Control
Most modern telecommunication protocols require the transmitter power to be adjusted over a wide range. This feature, commonly referred to as power control, ensures that adequate power is received by the base station, while conserving energy by reducing the transmitted power when the maximum transmitted power is not required and reducing the potential interference in other channels. Many wireless networks require that the transmitted power be adjustable over a range of as much as 20 dB.
