Abstract :
This paper presented a novel IntraBody Communication Receiver Front End (RFE) based on switched capacitor filter scheme with proposed sampling rate boosting technique. New technique aims to increase the oversampling ratio without rising system clock frequency to enhance the transmission performance. In this work, specifically, sampling rate is boosted 4 times with 50MHz system clock, which can reach 200MHz sampling frequency. Based on the measurement result, proposed RFE achieves a 2.5Mb/s data rate upon Return-to-Zero (RZ) coding, 170cm transmission distance and 4.14mW power consumption. Chip measurement results demonstrate the effectiveness of proposed technique and its advantages compared to other conventional receiver front end circuits.
