Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
