A 0.5V/22 mu W Low Power Transceiver IC for Use in FSC Intra-body Communication System

Abstract

This paper presents an integrated transciver chip for use in electro-static coupling intra body communication. A simplified circuit model was developed to analyze the channel characteristics. A Manchester code was used to increase signal energy. In front of the receiver, an inverter-based amplifier applies to amplify the received data. Then, a Clock and Data Recovery data develops to recover the transmitted data. The chip is fabricated using UMC 0.18um CMOS process with a chip area of 0.75 X 0.7 mm(2), power consumption of 22uW and a data transmission rate of 10M bit per second.
