Abstract

This paper presents the realization of the radio frequency (RF) power and data transmission for implantable micro-stimulators. This implantable device includes an internal RF front-end circuit, a control circuit, and a stimulator. A 2MHz AM modulated signal including the power and data necessary for the implantable device is received, and a stable DC voltage and digital data will be extracted to stimulate the neuromuscular stimulation. The stimulator is a current-source stimulator, which is capable to generate a wide range of stimulation waveforms and stimulation patterns for a nerve cuff electrode. In this paper, most of the integrated circuits for the implantable device have been proposed and verified by using Hspice according to the technology of TSMC 0.25 μm CMOS process.
