Abstract: This study deals with the design and implementation of an efficient sub-electronic circuits to power and transfer data to the remote bio-implantable devices. The proposed system is designed and implemented based on ASK modulation techniques operated with 10 MHz with modulation index 11.6%. The system consists of a modified ASK modulator a proposed self-tuning Class-E coil driver with 92.13% of efficiency and voltage-doubling rectifier with self-threshold cancellation to generate a stable 1.8 DC voltage to power the implanted remote electronic circuits. The OrCAD Pspice 16.2 Software using specter simulation with edit 0.35 um CMOS process is used to validated the design. Whereas, the simulation results of the self-tuning Class-E coil driver is simulated with NI MULTISIM 11. For farther testing and validation an experimental hardware simulation is also presented using National Instruments NI circuits design suit (Virtual ELVIS 11) compatible with NI LabVIEW.
