Herein, we present the design technique of a resonant rectifier for piezoelectric (PE) energy harvesting. We propose two diode equivalents to reduce the voltage drop in the rectifier operation, a minuscule-drop-diode equivalent (MDDE) and a low-drop-diode equivalent (LDDE). The diode equivalents are embedded in resonant rectifier integrated circuits (ICs), which use symmetric bias-flip to reduc...

Class E synchronous rectifier regulating the output voltage at a fixed switching frequency is presented, analyzed and experimentally verified. This rectifier is derived from a class E low dv/dt rectifier by replacing a rectifier diode with a controlled switch. The rectifier is driven by a sinusoidal current source, and the output voltage is regulated by vary the conduction time of the controlle...
