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 MHZ, and industrial scientific and medical (ISM) (13.56 MHZ), and low frequency 125-135 KHZ. The results show that the proposed class-E design could use the same values of C1, C2, L2 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.
