Nursing Care of the Pediatric Neurosurgery Patient

Powering active implantable devices is challenging.Implants must be small and have a long lifetime. Wireless power offers energy over the life of the device. Using integrated circuits for managing wireless power transfer allows for a small implant. Often when implemented in CMOS, a synchronous rectifier is used to achieve AC-DC conversion. Current spikes can occur in the rectifier and must be considered to avoid electromigration. This paper presents the analysis of the peak currents in the synchronous rectifier. Reducing the peak current can be achieved by decreasing the size of the rectifying transistors. We have developed and fabricated the control circuitry for a synchronous rectifier in XFABs XH018 180nm high voltage CMOS process. A finalised synchronous rectifier is being designed which will be used to confirm our analysis.
