This paper presents a high efficiency comparator-based CMOS rectifier for wireless power transfer in biomedical implant devices. By using a novel ON-OFF compensation technology, the conduction time of the switch can be optimized and the reverse current has been reduced efficiently. The proposed rectifier was verified using a standard 0.18μm CMOS process. Results shows that the rectifier can achieve...
The increasing need to incorporate complex control features in switched mode power supplies (SMPS) in a CMOS compatible environment has spurred the study of digitally controlled integrated dc-dc converters. Designers continuously examine various design considerations for the implementation of these power converters, including topology choices, digital vs. analog control scheme, power conversion efficiency...
This paper presents an investigation into the effects of the gate drive resistance on the losses of the MOSFET-snubber-diode (MSD) configuration commonly found in a power converter. An analytical loss model that takes the circuit stray inductances, MOSFET parasitic capacitances, and reverse-recovery characteristic of the freewheeling diode into consideration is derived to describe the interaction...
