An optimization technique to minimize crosstalk in multi-layered and multi-microstrip-line board of high-speed digital circuits

Designing a digital circuit with faster clock rates, low power consumption, and minimal interline-coupling (or crosstalk) needs a critical board-level optimization. This paper refers to a multivariable optimization technique using a spectral domain approach such that the crosstalk and signal-distortions in multi-layered, multi-conductor microstrip-lines can be reduced significantly. Simulated results show that the maximum level of crosstalk in all the sense-lines can be reduced at least by 42% as compared to the method(s) employing non-optimization techniques.
