    Abstract

    A single-inductor dual-output wireless power delivery receiver for small size battery-less applications is presented. The power delivery system uses two rectifiers connected to a receiving inductor switched by pseudo-random-sequence PWM (PRS-PWM) signal synchronized with induced AC voltage in the receiving inductor. The power delivery system can generate 8 V and 16 V with peak efficiency of 40 %. The maximum total transmitting power is 0.5 W. The test chip was designed and fabricated using 0.18um-CMOS with high-voltage (32V) LDMOS option.
