This paper presents an ultra-low-voltage high-efficiency interface circuit for energy harvesting, which features self-powered design and digital switch control. The proposed rectifier includes bridge rectifier and active diode. The former introduces self-driven switches and ultra-low voltage divider to reduce the voltage drop for wide output voltage swing. The latter adopts a common-gate comparator as switch control block to output a nearly digital signal, thereby improving dynamic response and antinoise ability. The entire circuit exhibits good conversion efficiency and stability. Its minimum input voltage is down to 225 mV. The maximum voltage efficiency reaches to 96.3%, supplying the output current of 29 µA and the output power of 15.43 µW. The maximum power efficiency is 96.5%, providing the output current of over 16.1 µA and the output power of 5.19 µW. The whole circuit consumes the power loss of 1.42 µW.

According to the difficult replacement and poor endurance of the battery for wireless sensor network nodes, a low-frequency vibration-based interdigital piezoelectric energy harvester and power regulating circuit (PRC) have been developed in this Letter. The proposed vibration pickup structure consists of a rectangular flexible frame and series of cantilever beams interdigitally bonded to it. An efficient autonomous PRC with the function of energy storage, switch control, voltage regulation was also proposed. Experiment results show that a maximise output power of 18.8 μW could be produced by the proposed vibration energy harvesting system. The system's energy conversion efficiency could reach up to 72.3%, which made it the promising candidate of power supply for low power micro electron devices.
