Many applications call for wide-range-tunable LC oscillators that can deliver a nearly constant-frequency, nearly harmonic-free output even when the circuit's output load changes. From a design ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

This LC meter circuit can measure coils and capacitors. When Lx or Cx is connected in the circuit the oscillator frequency will decrease and this decrease is measured by a frequency-voltage converter ...

NIMS succeeded in fabricating topological LC circuits arranged in a honeycomb pattern where electromagnetic (EM) waves can propagate without backscattering even when pathways turn sharply. These ...

Tesla coils are one of those builds that capture the interest of almost anybody passing by. For the naïve constructor, they look simple enough, but they can be finicky beasts—beasts that can bite if ...

The discovery and implementation of alternating current revolutionized the entire world little more than a century ago. Without it, we’d all have inefficient, small neighborhood power plants sending ...

A line of flex circuits based on liquid-crystal polymer (LCP) dielectric film provides several enhanced properties required for demanding flexible-circuit applications. The circuits offer dimensional ...

It is well established that the suprachiasmatic nucleus (SCN) is the circadian pacemaker for many behaviors, including the sleep–wake cycle 1. A great deal is known about mechanisms underlying ...
