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.

For an undamped LC circuit excited by an AC voltage source through simple phaser equations, we come to see that the circuit becomes short circuited at the resonant frequency. However if we analyze the ...

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 ...

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 ...

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 ...
