Abstract
In this paper a low-voltage vibration energy harvesting circuit with MPPT(Maximum Power Point Tracking) control is proposed. By employing bulk-driven technique, the minimum operating voltage of the proposed circuit is as low as 0.8V. The designed MPPT control circuit traces the maximum power point by periodically sampling the open circuit voltage of a full-wave rectifier circuit connected to the piezoelectric device output and delivers the maximum available power to load. The proposed circuit is designed using a
본 논문에서는 MPPT(Maximum Power Point Tracking) 제어 기능을 갖는 저전압 진동에너지 하베스팅 회로를 제안한다. 제안된 회로는 Bulk-driven technique을 적용하여 0.8V의 낮은 전압에서도 동작 가능하다. 압전소자의 출력단에 연결된 전파정류기의 개방회로 전압을 MPPT 제어회로를 통해 주기적으로 샘플링하고, 최대 가용전력 점의 전압을 부하에 전달한다. 제안된 회로는 0.35um CMOS 공정으로 설계되었으며, 패드를 포함한 칩 면적은
