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.
