Abstract

Guarded ground tracks are extensively used in high density routing for mitigation of crosstalk. However, these ground tracks can influence the electrical properties of the interconnect line also. We present a novel analytical model for extraction of line parameters of high-speed interconnect lines guarded by ground tracks. Based on the proposed model, transient response of such interconnect structures is presented. It is seen ground tracks can significantly affect the time-domain response of the interconnect lines. The computed interconnect circuit parameters are compared with finite-difference time-domain simulations. The proposed model can be practically used for time-domain analysis of microstrip lines also. The results obtained would be useful in design of high-speedin terconnections for MCM, RF and MIC related applications.
