This paper describes a full-wave rectifiers for energy harvesting circuit using vibration detector. The designed circuit operates only when the vibration is detected through the vibration detector and the active diode. When there is no vibration, the comparator is turned off to prevent leakage of energy stored in the $C_{STO}$. The energy stored in the capacitor is used to drive the level converter and the active diode. The energy stored in the capacitor is supplied to an active diode designed as an output power. The vibration detector is implemented with Schmitt Trigger and Peak Detector with Hysteresis function. The proposed circuit is designed in a CMOS 0.35um technology and its functionality has been verified through extensive simulations. The designed chip occupies $590{\mu}m{\times}583{\mu}m$.
