This video explains the function of inductors and how they store energy in a magnetic field when current flows through them. Inductors are essential passive components used to manage current changes ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...

Portable battery-operated electronic equipment is becoming packed with more features requiring larger amounts of power, leading to decreased operating times between battery charges. Innovations such ...

Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Here’s a step-by-step design of a resonant-coupled inductor employed in a PFC EMI filter that doesn’t impact power factor. Over the past 40 years many of my designs included Power Factor Correction ...

A few years ago, there was a stir about a new fundamental component called a memristor. That wasn’t the first time a new component type was theorized though. In 1948 [Bernard Tellegen] postulated the ...

Using circuit simulating software like SPICE can be a powerful tool for modeling the behavior of a circuit in the real world. On the other hand, it’s not always necessary to have all of the features ...

On the road to smaller, high-performance electronics, researchers have smoothed one speed bump by shrinking a key, yet notoriously large element of integrated circuits. Three-dimensional rolled-up ...
