Near-field Metamaterial-based WPT system can enable over coupling mode by improving the transmitter (TX)/receiver (RX) coupling. The use of a fixed frequency oscillator to supply this system results in poor efficiency when TX/RX distance changes. Instead, we propose the use of a free-running oscillator to track the frequency of peak efficiency when over coupling occurs. Moreover, we employ a frequency hopping technique to enable back-data communication. The proposed WPT system operates at 50MHz and consists of a free-running voltage-controlled oscillator (VCO) operating at 0.6 V voltage supply and an off-chip metamaterial-based LC tank at the transmitter (TX) side. At the receiver (RX) side, the WPT system consists of an off-chip metamaterial-based LC tank, a rectifier, and a transistor operated as a switch for back-data communication, as per our frequency hopping technique. A digital FSK demodulator was designed to demodulate the signal using 0.18µm CMOS technology. Simulation results show that the transmitted data was successfully recovered at the TX side, and thus confirmed the validity of the proposed concept. |
