A Multilevel Pulse-Width Modulated Class-E Power Amplifier
2019 IEEE Radio and Wireless Symposium (RWS), 2019This work reports a Class-E pulse-width modulated RF power amplifier that uses multilevel discrete supply modulation for base station applications. This work quantifies the efficiency roll-off in multilevel PAs and proposes that pulse-width modulated (PWM) class-E PAs offer the best efficiency roll-off and dynamic range, based on the efficiency profile

Analysis and Optimum Design of a Class E RF Power Amplifier
IEEE Transactions on Circuits and Systems I: Regular Papers, 2008A new analysis of a class E power amplifier is presented and a fully analytic design approach is developed. Using our analysis, all of the circuit currents and voltages and, hence, the power dissipation in each component is calculated as a function of a key design parameter, denoted by x.

Case Study : A class E power amplifier for ISO-14443A
2009 12th International Symposium on Design and Diagnostics of Electronic Circuits & Systems, 2009This paper reports on the design and implementation of a class E push-pull amplifier in order to increase the reading range of an ISO-14443A RFID system. With the aid of classical design formulas and some alterations due to parasitic and intrinsic capacitances, a working implementation was made that can provide the loop with an amplified modulated ...
