A Variable Audio Frequency Oscillator Using Op-amp 741
https://bestengineeringprojects.com/a-variable-audio-frequency-oscillator-using-op-amp-741/
The circuit of variable audio frequency oscillator using op-amp 741 is mainly a Wein Bridge oscillator whose frequency is varied using the gang condenser. While using the IC 1 741 (operational amplifier), the use of split power supply has been avoided by using capacitors C 1 and C 2, for R 4 *, a 150-Ω resistor, we can use thermister or even a bulb which control the …
OpAmp Oscillator Circuits Worksheet - Analog Integrated ...

There are more versatile op-amp models commonly available for the beginner. I recommend the LM324 for DC and low-frequency AC circuits, and the TL082 for AC projects involving audio or higher frequencies. As usual, avoid very high and very low resistor values, to avoid measurement errors caused by meter “loading”.

The op-amp based oscillator, which produces a sinusoidal voltage signal at the output with the help of an inverting amplifier and a feedback network is known as a RC phase shift oscillator. This feedback network consists of three cascaded RC sections. The circuit diagram of a RC phase shift oscillator is shown in the following figure −

The L and C values are chosen the same way as for the oscillator in Figure 1. On the other hand, the oscillator circuit in Figure 3 displays a decent choice for a very low-frequency, audio tone producer. Using the above op amp LC oscillator circuit, you can get tone frequencies under 10 Hz and even less than 1 Hz.

components around a central op amp. Op-amp oscillators are restricted to the lower end of the frequency spectrum because op amps do not have the required bandwidth to achieve low phase shift at high frequencies. Voltage-feedback op amps are limited to a low kHz range because their dominant, open-loop pole may be as low as 10 Hz. The new current-feedback op amps have a …
Relaxation Oscillator using Op-amp - Circuit Design & Working
https://circuitdigest.com/tutorial/relaxation-oscillator-using-op-amp
Operational amplifier is an integral part of Electronics, and we previously learned about Op-amps in various op-amp based circuits and also built many oscillator circuits using op-amp and other electronics components. Oscillator generally refers to the circuit which produces periodic and repetitive output like a sine wave or square wave.
