In recent years, measurement while drilling(MWD) and underground-oriented control technology have made great progress, and more and more sensors and control units are applied in down hole. For drilling equipment and downhole measurement tools which work for a long time in the underground, the stronger its functions and the more sensors and control actuators used, it means that the greater demands...
This paper presents a novel wireless integrated power management unit (PMU) for implantable biomedical telemetry systems. The PMU was fabricated in a 0.35μm CMOS technology occupying approximately 1×1 mm2. First, the presented unit can recharge implanted batteries via radio frequency power transmitted from an RF source. The charging voltage can be set in the range of 4.28V~5.3V for various batteries...
