摘要

本文设计并分析了一种2.4GHz的发射机。该发射器采用130纳米CMOS工艺制造，采用二进制相移键控(BPSK)调制，类似于Wi-Fi系统的最低比特率传输块。发射机工作在1.2V电源下，功率放大器的峰值功率效率为74.6%。它主要由上变频混频器、振荡器和功率放大器三个部分组成。

A 2.4 GHz high power efficiency BPSK RF transmitter for Wi-Fi in 130 nm CMOS

In this paper, a 2.4GHz transmitter has been designed and analyzed. Fabricated in a 130nm CMOS process, the transmitter employs binary phase shift keying (BPSK) modulation which is similar to the lowest bit rate transmission block of a Wi-Fi system. The transmitter is operating at a power supply of 1.2V and the peak power efficiency of power amplifier is 74.6%. It comprises of mainly three components, an upconvetrer mixer, oscillator and a power amplifier.
