Abstract: A power amplification controlling apparatus and method in a mobile communication system are provided. An amplifying part amplifies an input Radio Frequency (RF) signal with a power supply voltage. A bias adaptation part detects a change in at least one an operation and an environment of the amplifying part, attenuates the RF signal according to the detected change, detecting the envelope of the attenuated signal, and generates a supply voltage control signal according to the envelope. A power supply part changes the power supply voltage in response to the supply voltage control signal.

Abstract: An apparatus and method amplifies a delta-sigma modulated signal and delivers the amplified signal to a power amplifier without distortion in a communication system. The apparatus receives a delta-sigma modulated signal, phase-delays the received delta-sigma modulated signal by a multiple of 360° for a bandwidth of the delta-sigma modulated basic signal, and amplifies the phase-delayed signal, facilitating implementation of a high-efficiency delta-sigma modulation-based amplification system.
