摘要

This 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 current wave.
