Author: Amit Srivastava Abstract: Significant advanced development in the field of communication has led many designers and healthcare professionals to look towards wireless communication for the treatment of dreadful diseases. Implant medical device offers many benefits, but design of implantable device at very low power combines with high data rate is still a challenge. However, this device does not rely on external source of power. So it is important to conserve every joule of energy to maximize the lifetime of device. Choice of modulation technique, frequency band and data rate can be analyzed to maximize battery life. In this thesis work, system level design of FSK and QPSK transmitter is presented. The proposed transmitter is based on direct conversion to RF architecture, which is known for low power application. Both the transmitters are designed and compared in terms of their performance and efficiency. The simulation results show the BER and constellation plots for both FSK and QPSK transmitter. Number of pages : 43 Keywords: FSK, QPSK, Transmitter, Modulation, Efficiency, Constellation plot, Symbol rate, Low power.
