A Ternary Partial-Response Signaling Scheme for Capacitively Coupled Interface

Abstract

This paper describes a ternary partial-response signaling scheme for capacitively coupled chip-to-chip data transmission to increase data rate. Partial-response coding is known as a technique that allows high-speed transmission while using a limited frequency bandwidth, by allowing controlled intersymbol interference (ISI). Analysis and circuit simulation results are presented that compare this approach to two types of partial-response signaling, ternary duobinary (1+D) and dicode (1-D) signaling for capacitively coupled interface.
