A case study in body channel communication transceiver design for wireless applications

In this paper, the Body Channel Communication is used which is created by Microchip. Compared to existing wireless communication methods, microchip provides lower energy consumption and also provides high security. It complies with Federal Communication Commission part 15-B for radiated emissions. The time domain characteristics of this channel communication of human body are measured with an analog front end printed circuit board at different signal frequencies and at different transmission distances. Normally, the AFE is used to save power, increase speed design time, reduce board space and also increase reliability. Both high-speed and low-speed data-converters had been combined in a single device so the size, cost, and power can be reduced. In existing designs at transmitter part, the NRZI-encoded data are sent directly to the body channel. At receiver part, after an AFE, PCB amplified the received signals. It is implemented in 90nm CMOS process, the core area, the power consumption, and the bit energy is 0.144mm2, 1.21mW at 40mb/s and 0.03nJ/b respectively. Here, we are going to study about the previous work and made some assumptions to reduce the core area, power consumption and with energy efficiency.
