Design of the Dynamic Bias Control High-Efficiency Power Amplifier
동적 바이어스 조절 고효율 전력증폭기 설계
Abstract
In this paper, a 0.5W, 2GHz high-efficiency class A power amplifier using the dynamic bias control is proposed. First of all, the drain bias control amplifier is analyzed theoretically and designed with commercial devices. Simulation results show that the proposed amplifier has a significant improved efficiency, compared to fixed bias power amplifier.
