TRANSIENT ANALYSIS OF MICROSTRIP – LIKE INTERCONNECTIONS GUARDED BY GROUND TRACKS

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.
