A Fully Integrated AC-DC Converter in 1 V CMOS for Electrostatic Vibration Energy Transducer with an Open Circuit Voltage of 10 V

This paper proposes an AC-DC converter for electrostatic vibration energy harvesting. The is composed of a CMOS full bridge rectifier and shunt regulator. Even with 1 V CMOS, the open circuit voltage transducer can be as high 10 beyond. Bandgap reference (BGR) inputs regulated voltage, which controlled by output BGR. Built-in power-on reset introduced, minimize silicon area power to function normally found upon start-up. was fabricated 65 nm low-Vt 0.081 mm2. regulation measured successfully at 20–70 °C conversion efficiency 43%.
