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 ...

An LC voltage-controlled oscillator (VCO) is an electronic circuit that generates an oscillating output voltage whose frequency can be controlled by an applied voltage. It utilizes inductors (L) and ...

Abstract: This tutorial will go through the fundamentals of LC oscillator and LC VCO design, such as basic phase-noise theory, design for low power, low phase noise and, large tuning range (including ...

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 ...

The heart of this diy metal detector circuit is the CS209A IC. The metal detector is built with one 100µH coil that has 40 mm in diameter and is made of 50 turns/0.4 mm wire. CS209A has one oscillator ...
