Abstract
Using the energy harvested from the piezoelectric transducer to power on the electronic circuits in biomedical applications. The energy harvested is rectified by using the AC/DC converter with power efficiency 83% and the voltage conversion ratio reaches 300%. The DC/DC converter is used to match the output voltage of the AC/DC converter with thevoltageof supercapacitor 1.8V. The desired switching frequency range from 57KHz to 132KHz is generated using the voltage control oscillator that used a lookup table to guarantee that the frequency generated corresponding to the maximum power point. The output voltage of the AC/DC is digitalized to N-bits by using the successive approximation register analog to digital converter to build the lookup table
