Abstract :
Differential signaling has become a popular choice for multi-gigabit digital applications, due to its low noise generation and high common-mode noise immunity. This work describes a methodology to extract the equivalent circuits of the discontinuities for strongly coupled differential lines from the calculated full-wave S-parameters. The signal integrity effects of the bent differential transmission lines in a high-speed digital circuit are then simulated in time domain. A new way to reduce the common mode noise at the receiver by shunt compensation capacitances is also proposed.
