As the name refers to, oscillators are units which are designed to create oscillations or vibrations in a medium like, water, air or in a certain transmitting areas or network. In electronics, oscillators can be explained as circuits configured for emitting voltages at a specific predetermined frequency.
These frequencies are just make and break generation of positive and negative voltage peaks at a certain set or fixed time intervals.
Oscillator circuits have become the primary building sections of most high grade circuits presently, whether its your mobile phone, laptop or microwave oven, oscillators are introduced in all aspects of electronics circuits
In electronics the most fundamental form of oscillator configuration is the astable multivibrator circuit or the AMV.
Please rfer the CIRCUIT DIAGRAM for understanding how to make oscilator circuits.
This wiring basically consists of a reverse loop which gives rise in the development of a continuous chain of waves constituting the required oscillations.
Here we discuss a few interesting and easy to build oscillator circuits which may be applied in different areas like, for making buzzers, flashers, light blinkers, function generators, transducers etc.
The first circuit shows how an oscillator circuit can be built just by employing transistors.
The second circuit shows the regular form of an astable using the famous IC 555.
The further sections relate us with many different oscillator configuration using ordinary CMOS ICs.
