Abstract

Wireless sensor networks (WSN) is a wireless network composed of a large quantity of stationary or mobile wireless sensors nodes. This paper presents a power amplifier (PA) design for Wireless Sensor Network (WSN) in the frequency band of 2.4GHz~2.4835 GHzbased on 0.18 m RF CMOS process. The structure of fully differential current-mode Class D PA was used in this circuit, and in order to save power dissipation, the power control technique was adopted. The off-chip inductors and capacitances are used to achieve output matching and there is also an off-chip balun at the output of PA. Post-simulation results show that the PA can get output power ranging from -3.83dBm to 5.09dBm with power added efficiency (PAE) ranging from 12.7% to 35.5%.
