Crosstalk Reduction with Nonlinear Transmission Lines for High-Speed VLSI System

We report efficient crosstalk and signal reflection reduction with nonlinear transmission lines (NLTLs) for high-speed VLSI. Crosstalk measurements of NLTLs implemented with the Lincoln Lab 0.18mum FDSOI (fully-depleted silicon-on-insulator) CMOS process are performed in time domain as well as by S-parameters up to 25GHz. The excellent suppression capabilities on signal reflection, data-dependent timing errors and crosstalk without any circuit overheads in a broadband illustrate the advantage of the NLTL global interconnect
