Abstract :
This paper presents the design and experimental results of a wireless power receiver IC for the water pollution detection system. The system adopts the magnetic resonance method to transmit the wireless power. We adopts the active rectifier with dynamic body biasing scheme to implement the receiver. The receiver IC has been designed and fabricated in 0.35 um CMOS. Measurement results show that when the two coils have diameters of 9.5 cm and 2.2 cm and separated by a distance of 5 cm, the proposed wireless power receiver IC can supply 30.3 mW to a 400 Ω resistive load with a wireless power efficiency of 9.0%.
