This article describes the Sawtooth Wave Oscillator (TL082). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:TL082.

Sawtooth wave oscillatoris used in cathode ray tube deflection circuitry, in a PWM modulator, or in a analog to digital conversion. You can also use it in your own design, only your imagination can limit its application. Here is one example of the circuit:

sawtooth wave oscillator circuit schematic

The frequency is determined by C1, R1, R2, R3, and R4.? Thisfrequency formulacan be used to compute the frequency:

f=(1/2C(R1R2))x(R3/R4)

Be aware if the real frequency will be slightly different since the formula is only an approximation, and the components values might deviate at some tolerance.
