This paper presents a fully integrated system for implanted micro-system devices with efficient power and data transfer based on amplitude shift keying (ASK) modulation techniques. A proposed efficient class-E power amplifier is presented. The design presents a full transcutaneous inductive powering system to transfer power and data from an outside human body to implanted devices such as implanted microsystems to stimulate and monitor the nerves and muscles with low band frequency of 13.56 MHz according to the industrial–scientific–medical (ISM) band to avoid the tissue damage. A novel ASK demodulator powered with 1.9 V is proposed with a power recovery system. The modulation index is 13% and the modulation rate 7.3% with data rate 1 Mbit/s, and with power efficiency 66%. The system has been designed using 0.35-μm fabricated CMOS technology. The mathematical model is given and the design is simulated using OrCAD PSpice 16.2 software tool and for real-time simulation, the electronic workbench MULISIM 11 has been used to simulate the class-E power amplifier.
