Daniel Beeker is one of the top experts in the field of EMC and signal integrity. We met him during PCB West 2018 and asked him about his design techniques.
This article covers in-depth the topic of losses in PCB transmission lines. We will talk about conductor loss, signal trace resistance, dielectric loss, loss tangent/dissipation factor of a dielectric, and total insertion loss.
Released last month, the PerfectPulse J2151A is the fast edge signal generator and TDR you’ve been looking for. Made by Picotest, the Phoenix-based high-resolution test company, the PerfectPulse is the new low-cost measurement equipment that will change your life. Or at least your work life.
We previously quickly discussed signal reflection in our PCB Transmission Line series. This is an in-depth article about this very important topic that PCB designers should master. The first thing to remember is that reflections in transmission lines occur due to impedance discontinuity.
Today, we are going to talk about signal integrity. As a PCB designer, it is important for you to know the effects of via stubs on signal attenuation and data transfer rates.
A transmission line should have a uniform characteristic impedance. Any variation or discontinuities to the impedance causes signal reflection and distortion. Continue reading “How Impedance Discontinuities Affect Signal Integrity”
