Differential Pair Routing for SI and EMI Control

Differential pairs have been used in PC boards for years to carry high-speed serial and high-speed parallel data, in a variety of bus formats. Many board designers and engineers believe the rules... [more]

Millimeter-Wave Concepts Can be Used to Optimize the Performance of High-Speed Digital Circuits

Understanding millimeter-wave (mmWave) concepts can benefit RF designers, high-speed digital circuit designers and fabricators. In the RF industry, as frequency increases many circuit properties... [more]

How to Fight Magnetic Noise Gremlins

Have you ever had a noise-sensitive circuit and tried to find the noise source? Even after you completely encased sensitive portions in all sorts of shielding, you still had noise? It’s very... [more]

Designing the Signal Return Path

When designing a PCB, the signal routing and its return are critical to the circuit working properly. Great care is usually given to routing the signals, but often the return portion is the last... [more]
