Controlled impedance is not science fiction… Especially when you know how to calculate your controlled impedance traces. But, do you? Open our free Impedance Calculator – which will help you answer some of the following questions – and get ready to take the quiz!
During DesignCon 2018, Sierra interviewed Heidi Barnes, Senior Applications Engineer at Keysight Technologies. We asked her questions about power integrity, capacitors, and impedance.
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!
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.
Sierra Circuits will hold a two-day PCB design workshop led by PCB expert Robert Feranec on board layout design engineering for semiconductor manufacturing. The event will take place on May 17 and 18 at the Levi’s Stadium in Santa Clara, California.
After explaining the importance of the signal speed and propagation delay in a PCB transmission line, we are now going to talk about the transmission line effects, the critical length, the rise/fall time and when the length of an interconnection is to be considered as a controlled impedance transmission line.
