  • Abstract In recent years the science of biomedicine and the VLSI technology have fast development. Biomedical electronic devices which are used to be implanted in the human body have been developed. This paper uses MATLAB/SIMLINK for researching the demodulation circuits in Additive white Gaussian noise (AWGN) channel and the bit error rate (BER) of it. This thesis provides an analysis platform for further optimization and future design of the PSK demodulator for wirelessly implantable electronics.
    At present, the types of the implantable electronic devices tend to small and match the wireless way transmission techniques. Because the circuit is implanted, its internal power supply may be provided externally. Therefore, this paper takes focuses on the digital PSK demodulator with low power and small chip area.
    External transmitter transmits data only, while the clock is not transmitted. The PSK demodulator regains clock signal at the receiver by the incoming data envelope. Because the system with the PSK demodulator is implanted, a Q (quality factor)-independent CALSS-E power amplifier is designed PSK modulator in the transmitter. It can be effective to the high energy stored in the network, meaning the power consumption is small, and therefore increasing the demodulation difficulty. So the demodulator must be designed to be more complex. Therefore establishing a simulation test platform can greatly help the overall system’s research and facilitate development speed and efficiency.
