Push – Pull Amplifier – Push – Pull Amplifier Operation

Push – Pull Amplifier

A Push – Pull amplifier is called that way, because it uses 2 groups of transistors and only one works at a time. One group pushes in one direction while the other pulls in another direction. Each group is responsible for amplifying a single phase of the input wave.

Crystal Oscillators - Piezoelectric Oscillator. Equivalente circuit

Crystal Oscillators – Piezoelectric Oscillator. Equivalente circuit

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. In a similar way, a voltage applied on the faces of the crystal produces a mechanical distortion on their surface. An AC voltage causes […]

LC Oscillator - Inductance - Capacitance Oscillator

LC Oscillator – Inductance – Capacitance Oscillator

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 […]
