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]

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]

Does a Differential Pair Need a Return Plane?

A differential pair is any two transmission lines. When each transmission line has a return plane, its pretty clear how the differential impedance is related to the geometry. But what if there is no... [more]
