Abstract

In this study an efficient extraction energy based CMOS resonant rectifier is proposed for increasing the available output power of Piezoelectric (PE) transducer. A symmetric flipping circuit is used to extract energy from the transducer. Measured results show that the proposed rectifier significantly increases the extracted power when it is compared to the conventional full-bridge rectifier (CFBR). Moreover, results show that proposed rectifier has a flipping efficiency and power conversion efficiency of 77 % and 80 %, respectively. It is implemented in 0.18-μm CMOS process in a compact chip area of 0.072 × 0.136 mm2.
