A Serpentine Meander Delay Line with dumbbell-shaped stub

A dumbbell-shaped stub-loaded serpentine meander delay line (DSL-SMDL) is proposed in this paper. The DSL-SMDL increases the self-inductance and self-capacitance, which can raise the amount of delay and is mainly based on the theory of slow-wave. Meanwhile, this structure eliminates the far-end crosstalk (FEXT) by the ratio equalization of capacitance and inductance coupling.
