In this work, the channel communication of a human body which consists of characteristics in time-domain has been measured with the support of printed circuit board-an analog frontend board (PCB-AFE) at different signal frequencies and transmission distances. Furthermore, as the transmission medium, a human body skin is used with the signal of wideband Body Channel Communication (BCC) from 1 Mb/s to 40 Mb/s. While comparing with several methods of wireless transmission, this communication is low power in the attenuation and it is more stable. Additionally, this communication is unaffected to a human body motion. However, in the channel communication of human body, some interferences occurred by the effects of body antenna. The transceiver consists of transmitter and receiver parts where the encoded Manchester-data is sent through the channel of a human body then received signals is been amplified by an AFE-PCB. The circuit also consists of 7X sampler in clock data recovery to improve the quality of data. Therefore, the proposed Reconfigurable Frequency Synthesizer and Variable Cymometer (RCFS-VC) is processed in XilinxISE14.5, ModelSim Simulator 6.5a (Quartus II 8.1) and Micro wind software tools. It is also implemented in a XilinxXC9572XL kit. The power consumption and delay is reduced up to 90%, speed is increased up to 50% and leakage current is reduced up to 80% in the receiver part of the system.
