Differential Interconnects with Integrated Equalization and Common-Mode Filtering for Broadband Signal Integrity Enhancement in High-Speed PAM-4 Signaling
In high-speed differential interconnects on printed circuit boards, signal integrity (SI) issues arise when neglecting the inherent low-pass characteristic and ubiquitous presence of common-mode noise. This work proposes a novel open-circuited stub equalizer with integrated common-mode filter in order to compensate for the low-pass characteristic while simultaneously suppressing the transmission of unwanted common-mode noise to […]
