When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

Editor’s note: I am pleased to bring you this excellent tutorial by Steve Subiry, Global Products Manager for Magnetics at Eaton. Enjoy. Magnetics are essential components in power topologies but they ...

Capacitors, resistors, inductors, connectors, and even the printed-circuit board (PCB) are called passive because they don’t have gain or control power like semiconductors or other active devices (see ...

Any system is only as good as the sum of its components. Therefore it is important to understand how to go about choosing the right passive components to get the best system performance. At the end of ...

In the previous article, “The principles of RFID: Active Tags,” we discussed a classification of RFID tag called the active tag. Even though the active tag has many applications, it does not get as ...
