Introduction to Oscillators

A oscillator is an electrical or electronic circuit which produces a continuous periodic oscillating signal usually consisting of a sine wave. It is used in a variety of applications including television receivers, audio mixers, computer sound systems and more recently, microwave components. Oscillators are typically used in RF (Radio Frequency) systems for generating signals as well as for radio communication. Oscillators are also used in other electronic circuits where an AC (Alternating Current) voltage or current is needed.

Types of Oscillators

Oscillators are divided into two main types - tuned and untuned. Tuned oscillators use capacitors and inductors to provide a sinusoidal output, while untuned oscillators use resistors and capacitors to produce sine waves. Common types of oscillators include a wide variety of fixed-frequency oscillators, including crystal (or piezoelectric) oscillators, RC (Resistance-Capacitance) oscillators and LC (Inductance-Capacitance) oscillators. Other types of oscillators include voltage-controlled oscillators (VCOs), digital controlled oscillators (DCOs) and free-running oscillators.
