摘要

In this paper, a differentially-fed charge pumping rectifier design is presented with an enhanced efficiency for ambient RF energy harvesting. Due to the differential signals induced by a delicately designed rat-race coupler, circuit topology of the modified Greinacher rectifier is simplified with an enhanced RF-to-dc power conversion efficiency (PCE) over low power ranges. Meanwhile, high output DC voltage is sustained for the requirements of an efficient DC-DC boosting converter. Results of simulation and measurement validate that an enhanced efficiency of more than 5% is achieved over ultralow power ranges from -20dBm to -10dBm and the output DC voltage sustains with its amplitude more than 0.7V at incident power of -10dBm.
