A Simple Novel Wireless Integrated Power Management Unit (PMU) for Rechargeable Battery-Operated Implantable Biomedical Telemetry Systems

摘要：

This paper presents a novel wireless integrated powermanagement unit (PMU) for implantable biomedical telemetrysystems. The PMU was fabricated in a 0.35 μm CMOS technologyoccupying approximately 1×1 mm 2. First ,the presented unit canrecharge implanted batteries via radio frequency power transmittedfrom an RF source. The charging voltage can be set in the range of4.28V~5.3V for various batteries. The typical charging current is200uA. Second, it provides on/off switching through external wirelesscontrol. Third, it has an ultra low standby current about 5pA. Thesize is reduced by a simplified control logic circuit and one inductivelink coil to transfer the energy and data. The simplicity and modularfeature make it a useful power interface designed for rechargeablebattery-operated medical telemetry implants.
