SYNERGISTIC ENERGY HARVESTING TECHNOLOGY FOR AUTONOMOUS INTEGRATED SYSTEMS IN REAL ENVIRONMENT

在这项研究中，开发了一种协同能源收集技术，其中多个能源在同一地点同时可用，并以合作的方式利用。例如，已经开发出一种配备光伏(PV)电池的高频整流器，用于从周围的无线电波中高效地收集能量。作为光伏电池的p-n结二极管将光能转换为直流偏置电压，从而补偿MOSFET的阈值电压，并提高整流器的射频至直流功率转换效率(PCE)，即使在极低的输入功率条件下也是如此。

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.
