Abstract: This study present designing an integrated voltage tripled circuit using piezoelectric vibration generator. Energy harvesting from the ambient source for powering micro devices have been increasing the popularity. These types of devices can be used in embedded applications or in wireless sensor networks where battery replacement is improbable. Piezo bending generator generated 1 V from force vibration has been experimentally tested. Most of the previous techniques are mainly both passive and active based energy harvesting circuits. In this research the passive technique have been proposed to design the proposed circuit. The developed voltage doubler and tripled circuit integrated with full-wave diode bridge rectifier circuitry have been designed and simulated using MATLAB/Simulink. The developed voltage doubler circuit is generated 1.5 V and the developed voltage tripled circuit is generated 2.5 V. Finally, the achievement of integrated development circuit is provided a regulate DC output voltage of 1.5 V for the input AC voltage of maximum 1 V. The overall circuit efficiency is >90% following the simulation results.
