All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Analog Devices references guard shields around their op amps as well as the printed circuit traces [1]. These traces are called guard rings; they circle and shield critical circuits. Another ...

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

Thevenin and Norton equivalent circuits [1-3] are a valuable analytical tool for circuit designers and researchers. How to obtain the Thevenin resistance and Norton conductance of a network with ...

Inductors range from RF coils used in communications through switchmode inductors used in power supplies and differential and common mode inductors in EMI filters. As switchmode power supply designs ...
