ABSTRACT As integrated circuit technology advances, implantable biotelemetry devices will be able to handle more complex functions. Their flexibility and performance can be increased by incorporating multi-rate and multi-modulation schemes. The Class-E transmitter has been a primary choice so far in implantable devices as it provides low-power design with high-power efficiency. This paper investigates the design procedures of class-E amplifier for different modulation schemes in biotelemetry systems. A Class-E transmitter circuit that produces OOK, FSK and PSK modulated signals has been designed, optimized and analyzed in terms of a second order system for general implantable electronics.

    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 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.

    ABSTRACT: Biomedical implanted systems require wireless technology to transfer data and power to the implanted devices. This paper compares the performance and suitability of the ASK, FSK, PSK, OOK and PWM-ASK modulation schemes in implantable devices. Simulations illustrate that the best scenario for power and data transmission is obtained using PWM coded ASK (PWM-ASK) with the 0 bit transmitted as a 50% duty cycle, and the 1 bit transmitted as 90% duty cycle. The latter is the most popular and promising system due to the low power requirement for the receiver while providing a decent BER compared to traditional modulation schemes: a comparison of the power transmission level of PWM-ASK shows a 53.4% power increase compared to OOK modulation.

    ABSTRACT: Using Pulse-Width Modulation Amplitude-Shift Keying (PWM-ASK) in biomedical implants enables the simultaneous transmission of wireless energy as well as data using a single inductive link. This paper approaches Pulse-Width Modulated Amplitude-Shift Keying (PWM-ASK) from a communication theory point of view. It provides a design methodology to obtain high data rate while maintaining an optimal BER (Bit Error Rate), and optimal power transfer in biomedical implants.
