Abstract
This paper presents a simple and robust method of designing the lossy-transmission-line interconnects for multichip modules (MCM). This method uses wire-sizing to meet the electrical damping criteria to propagate high-speed signals through unterminated lossy transmission lines on the substrates of multichip modules. Based on an improved scattering-parameters (S-parameters) macro-model of transmission lines, wire-sizing optimal design method relates the layout parameter (line width) and the transfer function (damping ratio, and natural undamped frequency) to the signal propagation delay. The optimal design method results in fast and stable signal propagation for single-source multi-receiver networks on multichip modules without using termination resistors.Keywords
