Abstract
This paper presents a Differentially-Driven Rectifier (DDR) for Radio Frequency (RF) energy harvesting system at WLAN frequency 2.4 GHz. This rectifier converts the RF signal into direct current (DC) voltage at the given frequency band. A parameter-S and transient analysis on rectifier circuit is carried out to investigate its band, efficiency and output voltage. The optimum parameters including the value of capacitance, inductance and load value are calculated with HSMS-2850 Schottky Diode. Simulation and measurement results are presented that passive component based circuit can significantly increase the RF input voltage and broaden the input range of the rectifier. The DDR simulation results the efficiency up to 75.65% and 3.58 V output voltage at 10 dBm input power. Meanwhile, the measurement results show efficiency up to 56.39% and 1.01 V output voltage at the same input power.
