Introduction to Oscillators

Oscillators are devices used for various purposes in electronic circuits. They are typically used to generate electrical signals that have a specific and repeatable shape. Oscillators can be used for timing, frequency control, voltage regulation, data conversion, clock synchronization and other applications. Generally, oscillators can be classified into two broad categories: analog oscillators and digital oscillators.

Analog Oscillators

Analog oscillators generate an analog output which is an electrical waveform, usually at a specific frequency. This signal is usually generated using LC or RC circuits and can be described by the equation for the voltage of the output signal. Together with a feedback path, this loop forms the basis of numerous different kinds of analog oscillators. Although these oscillators are simpler to design than digital oscillators, the output signals are often not suitable for many applications due to their lower frequency accuracy and their increased susceptibility to noise.

Digital Oscillators

Digital oscillators use digital techniques for generating the output waveform. They usually utilize multiplexers, shift registers, or phase-locked loops for creating the desired signal. Digital oscillators have advantages over analog oscillators in terms of frequency accuracy, dampened frequency drift, low noise, and the ability to be controlled using software. In oscillator applications, they increase the overall performance of a circuit due to their higher stability and precision.
