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]

PCB Design of Power Distribution and Decoupling

Power distribution in PCBs is the foundation around which all things work in the circuit. If this is not designed correctly, the entire circuit is at risk from noise and signal integrity issues, to... [more]

Mechanical Design to Control EMI

As most engineers and designers are aware, EMI occurs because some mechanical structure, within or attached to our system, is capable of resonating and radiating electromagnetic field energy. Those... [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]
