**ABSTRACT:**This paper discusses the simulated exposure to a 5 MHz electromagnetic field powering implanted electronic devices using an inductive link. A high efficiency class-E transmitter circuit operating at 5 MHz has been designed. The circuit generates a 1 W to 5 W transmitted power by means of two possible planar primary coil designs, and powers 5 identical implants which are individually equipped with a secondary inductor. Simulations illustrate that a maximum localized SAR level (averaged over 10 g) of 1.16 W/kg is obtained in a rectangular bone structure with a thickness of 10 mm, when the power transmission is equal to 5 W.01/2012; -

**ABSTRACT:**This paper introduces a modified an efficient design for different Class-E power amplifiers suitable to be use in biomedical implantable devices and in biomedical wireless telemetry devices which is usually have a small load resistor (several Ohms) due to its inductive powering. The different Class-E amplifiers operated according to the frequency chart for the medical implant communications service (MICS) 27 MH Z, and industrial scientific and medical (ISM) (13.56 MH Z), and low frequency 125-135 KH Z . The results show that the proposed class-E design could use the same values of C 1 , C 2 , L 2 for small and optimum load resistor with high efficient more than 80% All these three class-E power amplifiers will be presents in this work and will be simulate with the MATLAB/SIMULINK environment, and for further verification all the circuits will be simulated with electronics workbench MULTISIM 9.2012 IEEE International Conference on Biomedical Engineering (ICoBE); 02/2012 -
