摘要

本文设计了一种适用于极性功率放大器包络调制器的ab类功率放大器。极性调制是射频功率放大器效率提高技术中最常用的一种。ab类功率放大器是混合开关包络调制器的主要组成部分，被称为线性高效包络调制器结构。高直流增益、宽带宽、低输出阻抗(ab类)的设计是HSEM设计的重要内容。本文讨论了一种适用于10mhz OFDM信号的ab类放大器的设计，该放大器采用0.18 μm CMOS技术。ab类放大器的直流增益约为94 dB，单位增益带宽为704 MHz，单位增益为0.25,20MHz时为负反馈输出阻抗。

Design of a rail-to-rail, low output impedance class AB power amplifier for envelope tracking of polar modulators

This paper presents the design of a class-AB power amplifier suitable for envelope modulator of polar power amplifiers. Polar modulation is one of the most popular RF power amplifier efficiency enhancement techniques. Class-AB power amplifier is a main building block of hybrid switching envelope modulator which is known as linear and efficient envelope modulator architecture. Design of high DC gain, wide bandwidth, low output impedance class-AB is important in the design of HSEM. In this paper the design of a class-AB PA suitable for 10 MHz OFDM signals will be discussed in a 0.18 μm CMOS technology. The class-AB PA has approximately 94 dB DC gain, 704 MHz unity gain bandwidth and 0.25 unity gain negative feedback output impedance at 20MHz.
