When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

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 ...

Researchers at the University of Illinois, Urbana-Champaign have devised a method of combining capacitors and inductors in a tiny, 3D rolled membrane. This will save space in the electronic filters ...

In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...

In 1971, Professor Leon Chua described and named the memristor, arguing that it should be included along with the resistor, capacitor and inductor as the fourth fundamental circuit element. The ...

Direct current-to-direct current (DC/DC) converters with faster switching frequencies are becoming popular due to their ability to decrease the size of the output capacitor and inductor to save board ...

Mathieu Renaud, Senior Power Management Designer, Intégration Dolphin Inc. Yves Gagnon, Executive Director, Intégration Dolphin Inc. Inductor-based Switching Regulators (SR) have historically ...
