Handle Crosstalk in High-Speed PCB Design

Signal integrity measurements have become a critical step in the process of developing digital systems. Signal integrity problems such as crosstalk, signal attenuation, ground bounce, etc., increase at higher frequencies where transmission line effects are also...

How to Reduce Signal Attenuation in High-Speed PCBs

How to Reduce Signal Attenuation in High-Speed PCBs

When a signal travels from the source towards the load through a PCB conductor, it experiences attenuation due to trace resistance and dielectric loss resulting in energy loss. Signal attenuation is the most prevalent term when high-speed signals propagate on a...

Losses in PCB Transmission Lines

Losses in PCB Transmission Lines

A PCB transmission line comprises at least two conductors – one for the signal and another for its return path. Complex circuit board nets are the combinations of such simpler transmission line structures. Understanding these structures (microstrip, stripline, and...

How TDR Impedance Measurements Work

How TDR Impedance Measurements Work

Measuring impedance and checking for faults and discontinuities on different points of a PCB trace is not a cakewalk. This is because impedance is an AC property and cannot be measured like resistance. Time Domain Reflectometer (TDR) impedance measurements are...

How to Avoid Crosstalk in HDI Substrate?

How to Avoid Crosstalk in HDI Substrate?

Miniaturization of the copper features in electronic circuits results from placing interconnections closely with a high packing density. As a result, crosstalk in HDI PCB substrate comes at play because of the increased coupling between the adjacent signal lines. HDI...

The Effects of High-Speed Signals in a PCB Design

The Effects of High-Speed Signals in a PCB Design

The designers are constantly challenged to improve the performance of an electronic product. At the same time, the designers need to consider the effects of high-speed signals in a PCB design since continuously increasing clock frequencies and decreasing rise times...
