Study of Crosstalk and Distortion of High Speed Pulses in Digital Circuits

摘要

Crosstalk and distortion of high speed pulses due to multiple reflections are studied. The moment method is used to solve for the currents and charges on a set of parallel microstrip transmission lines. Next, these solutions are employed to construct the capacitance and inductance matrices for the system. A modal analysis of an n-line transmission line system is used to evaluate the dependence of crosstalk on line spacing and inpute pulse risetime. Other results are given which demonstrate the difficulty of obtaining accurate data for poorly matched loads.
