本文提出了一种改进的C类放大器发射电路，并对四种谐振回路拓扑进行了比较，给出了电路设计和利用LTspice仿真软件进行的功率效率计算。发射机电路由5V输入电压、C类放大器、改进的LTC 6992栅极驱动N-晶体管和谐振电路组成。另一方面，接收电路由谐振回路、带二极管肖特基二极管的全波整流器和电阻作为负载组成，电阻值在1到2，kΩ之间变化。结果表明，当电阻为63，Ω，耦合系数为0.99时，发射端并联接收端串联的谐振回路具有最高的功率效率和输出电压，其值为32.74%.此外，该电路设计具有250 kHz的谐振频率发射器和接收器，这包括在电源事务联盟法规和宽带无线论坛日本指南中。
In this paper shows modified circuit of class-c amplifier as transmitter part and comparison of four resonant tank topologies as state of the art. The circuit design and power efficiency calculation using LTspice simulation software. The transmitter circuit is consist of 5 volt as input voltage, class-c amplifier, modified circuit LTC6992 as a gate drive n-mosfet and resonant tank. On the other hand, the receiver circuit consist of resonant tank, full wave rectifier with diode schottky which is a high efficiency diode and resistor variable as load which the value changed from 1 to 2,kΩ. The result shows resonant tank parallel in transmitter and series in receiver has the highest power efficiency and output voltage compared to the other topology with value 32.74% when resistance around 63, Ω and coupling coefficient 0.99. In addition the circuit design has resonant frequency transmitter and receiver in 250 kHz which included in power matters alliance regulation and broadband wireless forum Japan guidelines.
