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 ...

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

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 ...

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 ...

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 ...

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 ...
