Title: Apparatus and method for power amplification in wireless communicaton system
Inventor: SUN KAE OH
IPC: H03F3/20
Filed: 2007-10-02
Abstract: An apparatus and a method for amplifying the power in a wireless communication system are provided to perform the power amplification with high efficiency and high linearity by compensating a quantization noise by an error amplifier. An envelop generating unit(320) generates an envelope signal from an RF(Radio Frequency) signal. A switching controller generates a first switching control signal by delta-sigma modulating the envelop signal. The switching controller generates a second switching control signal by amplifying an error signal by the difference between the envelope signal restored by filtering the modulated envelope signal and an original envelope signal. An amplifier unit(360) amplifies the phase signal according to a first switching control signal and outputs a first output signal. The amplifier amplifies the phase signal according to a second switching control signal and outputs a second output signal.
