Signal Integrity Analysis and Equalizer Design for High-Speed Interconnects in Industrial Personal Computer Mother Board

There are many discontinuities in the industrial personal computer printed circuit board, such as the via and pad. As the transmission data rate exceeds several Gbit/s, the discontinuities have the serious impact on the signal integrity.
To improve the signal integrity on the eye-diagram performance of high-speed channel interconnection, this thesis used the resistor and inductor attached at the via stubs as an equalizer and proposed a design flow, accordingly. The design flow was verified between the simulation tools, scattering parameters, and eye measurements. To reduce the reflection noise, this thesis used the defected ground under the pad and the differential vias with the capsule-shaped anti-pad.
