|---|---|---|
This paper proposes a clocked AC-DC voltage multiplier to enable full integration of power converters into a sensor/RF chip even with low voltage micro-watt vibration energy harvesting such as electromagnetic or magnetostrictive energy transducer operating at a low resonant frequency of 10Hz-1kHz. Relationships of output voltage-output current and input current-output voltage are also formulated together with the open circuit voltage amplitude and the output impedance of the transducer. The modeling and the performance of the proposed voltage multiplier are validated by SPICE simulation and measured results of the prototype chip fabricated in a 65nm 1V CMOS process. As a result, the proposed integrated circuit can output a target power of 3.8μW at an output voltage of 2V from a magnetostrictive energy transducer with an available output power of 63μW and an output impedance of 500Ω. |
