The wireless power transfer (WPT) circuits are very promising to conduct therapy in several conditions especially in neurological stimulation. In the WPT designs, a high efficiency rectification and a DC output regulation are performed simultaneously using active rectifier without the need of an additional regulating circuits. However, the significant ripple appeared at the DC output voltage waveform so that reducing the efficiency of the rectifier. This is due to the application of NMOS as a switching device, where the threshold voltage of NMOS is strongly influenced by the body bias voltage. In this paper, the design of the active class E rectifiers using PMOS switch produces the DC output voltage waveform with an average ripple over 0-100% duty cycle is 16.7%. With simple structure and compact size, this proposed active class E rectifier can be applied for the future Hybrid WPT applications especially in low power operations.
