Design of 2.4GHz Two Stages Cascode Class E Power Amplifier for Wireless Application

Abstract

Abstract A low-power consumption internet-connected device has received considerable attention in recent years. Power amplifier (PA) is the most significant block in radio frequency (RF) transceivers because the PA consumes high power. Therefore, an efficient and low power consumption (PA) are necessary for wireless applications. This paper presents the design of 2.4 GHz two stage with cascode class E power amplifier for wireless application using CMOS 0.13-μm technology. The proposed design employed two stage topology with cascode class E configuration in order to achieve high efficiency. The simulation results show that the proposed PA delivers 35 % power added efficiency (PAE) and 22.6 dBm output power with 3.3 V power supply into a 50 Ω load.
