Abstract:
This article proposes a power management circuit for wireless energy transmission and power supply of wearable devices. As the wearable device becomes smaller and smaller, a power management circuit based on a switched capacitor network and a β-Multiplier Voltage Reference circuit is designed. The circuit structure of the chip is fabricated by SMIC0.18 μm CMOS process, and its power characteristics and RF signal are analyzed theoretically and experimentally. The operating frequency range of the circuit is 800MHz-1.5GHz, the output voltage of the power supply is stable 1.8V, the total is less than 16μw, and it can be effectively controlled by the radio frequency signal. © 2018 IEEE.
