Gustavo Blando: “A ground via next to a differential pair can reduce the amount of crosstalk”

During DesignCon 2018, we met with Gustavo Blando, Senior Principal Engineer at Oracle. We discussed material characterization, transmission lines, differential pairs, how placing vias can reduce crosstalk… among other things!

How to Analyze a PCB Transmission Line?

After establishing what a PCB transmission line is and talking about signal speed and propagation delay, last week, we discussed the critical length, the controlled impedance, and the rise/fall time of a PCB transmission line. Today, we are going to explain how to analyze a PCB transmission line using quantities, such as voltages and currents, and line parameters, such as resistance, inductance, capacitance, and conductance.
