This paper presents an RF rectifier circuit for electromagnetic energy harvesting system. The double voltage rectifier together with the super capacitor are employed to harvest the electromagnetic energy. The proposed circuit is designed to operate at 5.8 GHz Wi-Fi frequency band. The Schottky diode SMS7630-061 is used to implement the proposed rectifier circuit. The super capacitor 5 V with capacity...
A design of a wireless battery charging (WBC) system for a mobile phone device is reported in this paper. The objective of this design is low cost and low complexity of the electronic circuit and antenna system. The E-class power oscillator is chosen because of low complexity and high power efficiency. The Class-E power amplifier integrated with RC clock crystal oscillator is employed. Transmitting...
