应用于无线传感器网络的功率放大器的设计
Design of Power Amplifier for 2.4-GHz Wireless Sensor Network Applications
摘要
Abstract
This paper provides a power amplifier(PA) design for Wireless Sensor Network(WSN) in the frequency band of 2.4 GHz ~2. 4835 GHz, based on TSMC 0. 18-|xm RF CMOS process. The structure of fully differential Class AB cascode was used in this circuit,and in order to save power dissipation,the power control technique was adopted. The on-chip inductors and capacitances are used to achieve input matching and the means of loadpull is used at the output of PA for the maximum output power. The simulation result indicates that under 1.8V power supply,the output power is in the range of -10.4 dBm to 5.69dBm when the input power is -12.5 dBm,the power gain is 19.38 dB,the input reflection coefficient is about -30 dB,the output 1 dB compression point is 11.73 dBm and the power added efficiency is 33.75% at 1 dB compression point,the power consumption is about 12 mW.关键词
