Abstract
This paper describes a mixed signal subsystem for the inductive transfer of power and data to a fully-implantable medical device. The design includes circuits for the inductive power recovery and energy storage (charging), in addition to data recovery and demodulation. The data link is used to upload (at a data rate of up to 180Kbps) calibration and configuration data to the implanted device and integrates both error detection and correction on the recovered bitstream. The system incorporates an implanted Li-Ion micro-battery with supporting charging hardware to provide an uninterrupted power supply for autonomous deployment. This is to provide continuous operation without the requirement for an externally worn unit and additionally ensures registry (i.e. patient calibration) settings are maintained. The circuit has been implemented in a commercially available 0.35um CMOS technology without requiring high-voltage device options.
