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(More)
A low cost molded MMIC in a QFN package is designed and fabricated for a Ku-band high power amplifier. The generic plastic-molded QFN package contributes to the reduction of the assembly cost. To achieve high reliability with respect to humidity, the MMIC chip is covered with SiN passivation and polyimide coating. The MMIC circuit is designed with accurate(More)
