A 12-Gbs Non-Contact Interface With Coupled Transmission Lines Tsutomu Takeya St

Abstract

This paper presents a high data rate, non-contact in- terface using a coupled transmission line (CTL) composed of two differential transmission lines. The proposed CTL can achieve a measured loss of dB and a 3-db bandwidth of 3.4–9.0 GHz as a non-contact channel for a 1-mm communication distance. This wideband characteristic makes it possible to achieve high-speed communication using a single channel. The hysteresis buffer-based receiver recovers the transmitted data from the distorted wave- for
