What is an oscillator circuit?
An oscillator is a circuit which produces a continuous, repeated, alternating waveform without any input. This current flow through the circuit continues until the electromagnetic field collapses which result in the back-conversion of electromagnetic energy into electrical form, causing the cycle to repeat.
What is the function of oscillator circuit?
An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave or a triangle wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal.
What is oscillator used for?
An oscillator is a mechanical or electronic device that works on the principles of oscillation: a periodic fluctuation between two things based on changes in energy. Computers, clocks, watches, radios, and metal detectors are among the many devices that use oscillators.
How an oscillator converts DC to AC?
Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. Oscillators are often characterized by the frequency of their output signal: A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below approximately 20 Hz.
What are the basic requirements of a oscillator?
The basic requirements for oscillations are:
- The oscillator requires amplification to provide the necessary gain for the signal.
- To sustain oscillations, the oscillator requires sufficient regenerative feedback.
How does a relaxation oscillator work?
A relaxation oscillator is a repeating circuit (like the flasher circuit illustrated above) which achieves its repetitive behavior from the charging of a capacitor to some event threshold. The event discharges the capacitor, and its recharge time determines the repetition time of the events.

What are the basic components of an oscillator circuit?
It has basically three major components which are: (i) tank circuit (ii) amplifier and (iii) feedback circuit, It can be clearly seen in the block diagram given below: Continuous oscillations are the idea of working on an oscillator. Sometimes, an oscillator is claimed to be an amplifier with regeneration.
