Rapid progress in integrated circuit technology has led to an increase in switching speeds of digital circuits. This increase is the primary reason why inductance noise causes chips to fail. As a result, there is a growing interest in the inductance associated with on-chip signal lines. In this paper, we present the electromagnetic analysis we have followed in order to determine the accurate values of the equivalent parameters from which a set of multiple coupled transmission lines could be modeled. We then determine the most critical parameters which make the induc-tance effect important and we propose a new analytical expression to accurately evaluate the crosstalk voltage.
