Research Abstract

In this study, a synergistic energy harvesting technology, in which multiple energy sources being simultaneously available at the same place are utilized in a cooperative manner, has been developed. As an example, a high frequency rectifier equipped with a photovoltaic (PV) cell has been developed for highly efficient energy harvesting from ambient radio waves. A p-n junction diode acting as a PV cell converts light energy to a dc bias voltage, which compensates the threshold voltage of the MOSFETs and enhances the RF to DC power conversion efficiency (PCE) of the rectifier even under extremely low inputpower condition.
