Abstract

A single-ended current-mode interface circuit with a single-rail wire is proposed for a high-speed and highly reliable inter-chip communication link in an asynchronous network-on-chip system. The impedance of the single-rail wire is matched to the impedance of the receiver by inserting the MOS transistors, and the current signal level on the link is enlarged in the proposed interface circuit. As a result, crosstalk noise superposed on a single-rail wire can be reduced. It is demonstrated that the noise influences are eliminated under 130nm and 65nm CMOS technologies.
