Resumen
Descripción
Crosstalk is a signal integrity effect that negatively
impacts high-speed digital designs, especially those with dense
routing. Several techniques have been proposed to reduce
crosstalk. One of them consists of using innovative microstrip
structures, such as the stub-alternated and the serpentine
structures, which are intended to reduce far-end crosstalk.
However, these structures also present a negative effect on return
loss and near-end crosstalk. In this paper, these two structures
are optimized for far-end crosstalk reduction while minimizing
their negative impact on reflections and near-end crosstalk. A
genetic algorithm complemented with the Nelder-Mead method
is employed for direct optimization, using highly accurate EM
simulations in Sonnet driven from Python.
