Along with the development of the Internet of Everything (IoE), miniaturized piezoelectric vibration-energy harvesters have drawn significant recent interest as a means of harvesting ambient kinetic energy to power wireless sensors. As the energy generated by a piezoelectric transducer (PT) cannot be directly used, an interface circuit is needed to rectify the generated power and provide a stable supply. Fullbridge rectifiers (FBR) are widely used due to their simplicity despite their low energy efficiency. Recently, various interface circuits have been reported [1-5] to improve power efficiency, such as the SSHI (Synchronized Switch Harvesting on Inductor) rectifier. However, most of these reported circuits require large inductors to achieve good performance, and these inductors significantly increase the system volume, counter to the requirement for system miniaturization. Although a flipping-capacitor
