Abstract

This paper describes the design and the simulation results of the RF CMOS Class-E Power Amplifier for a 2.4GHz ISM band. This circuit is composed two connected amplifiers. where Class F amplifier drives Class E amplifier. The proposed circuit can reduce the total power dissipation of the driving stage and can work with higher efficiency. The power amplifier has been implemented in a standard $0.25{\mu}m$ CMOS technology and is shown to deliver 100mW output power to load with 41% power added efficiency(PAE) from a 2.5V supply.
