Abstract

A single-inductor dual-output wireless power delivery system for small size battery-less NAND flash memory card is presented. The power delivery system uses two rectifiers connected to a single inductor which is synchronously switched by pseudo-random-sequence PWM signal with induced AC voltage. The power delivery system can generate 8 V and 16 V with peak efficiency of 40 % and maximum total transmitting power of 0.5 W. The test chips were designed and fabricated using 0.18um-CMOS with high-voltage LDMOS option.
