Most simple circuits you'll find for measuring reactive components cover only a limited range of component values. Here's a circuit built from a handful of inexpensive parts that will let you measure ...

Of the three basic passive components—resistors, capacitors, and inductors—inductors are the least ideal and, therefore, the most difficult to model. The importance of a good model is that it not only ...

Adding a T-coil inductor and capacitor combo to your amplifier will extend its bandwidth. These circuits are also useful in high-speed digital I/O and video distribution. A T-coil is a special form of ...

New hybrid components could shrink the size of electronic filters used in communication devices. Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining ...

Most modern electronic devices consist of several key components: transistors, capacitors, resistors, inductors and diodes. Often, they are supplemented by additional components like crystals and ...

In modern industrial and household applications, single-phase motors are widely used due to their simple operation and low cost. However, effectively adjusting their speed is a common challenge. This ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...

When current flows through a conductor it becomes an inductor, when there is an inductor there is an electromagnetic field (EM). This can cause a variety of issues during PCB layout if you don’t plan ...

Amateur Radio as a hobby has a long history of encouraging experimentation using whatever one might have on hand. When [Tom Essenpreis] wanted to use his 14 MHz antenna outside of its designed ...

The three-dimensional (3D) additive printing process has attracted great interest in the field of rapid prototyping for a variety of applications due to its flexibility in geometrical designs and ...

Researchers have identified a new circuit element known as a meminductor. Dr. H. Rusty Harris, associate professor in the Department of Electrical and Computer Engineering at Texas A&M University, has ...
