Transcutaneous Inductive Powering Links Based on ASK Modulation Techniques

This paper presented a modified efficient inductive powering link based on ASK modulator and proposed efficient classE power amplifier. The design presents the external part which is located outside the body to transfer power and data to the implanted devices such as implanted Microsystems to stimulate and monitoring the nerves and muscles. The system operated with low band frequency 10MHZ according to industrialscientific – medical (ISM) band to avoid the tissue heating. For external part, the modulation index is 11.1% and the modulation rate 7.2% with data rate 1 Mbit/s assuming Tbit = 1us. The system has been designed using 0.35-μm fabricated CMOS technology. The mathematical model is given and the design is simulated using OrCAD P Spice 16.2 software tool and for real-time simulation, the electronic workbench MULISIM 11 has been used. Keywords—Implanted devices, ASK techniques, Class-E power amplifier, Inductive powering and low-frequency ISM band.
