Crystal Oscillators – Piezoelectric Oscillator. Equivalente circuit

Marcel — Fri, 19 Sep 2014 00:57:31 +0000

The Crystal Oscillators (Piezoelectric Oscillator) A quartz crystal has a property called: piezoelectric effect. This effect causes, by applying a mechanical pressure on the surface of the crystal, that a voltage is developed on the opposite sides. Similarly, a voltage applied on the faces of the crystal produces a mechanical distortion on their surface. An AC voltage causes mechanical vibration whose [...]

LC Oscillator – Inductance – Capacitance Oscillator

Marcel — Fri, 19 Sep 2014 00:46:34 +0000

LC oscillator: Inductance – Capacitance Oscillator A simple oscillator can be built with an amplifier stage and an inductive-capacitive network (LC) to provide an offset of -180°. The oscillation frequency can be freely adjusted or tuned on a range of frequencies from 100kHz to a few hundred MHz by changing only the value of C or L. These LC [...]
