Oscillator Circuit Op Amp. The op amp multivibrator circuit however can provide us with a good rectangular wave signal with the use of just four components three resistors and a timing capacitor. Op amp based oscillators are normally used to generate precise periodic waveforms like square sawtooth triangular and sinusoidal.

The circuit design must also involve an energy storing device like a capacitor or inductor which charges and discharges continuously to produce a cycle. As usual avoid very high and very low resistor values to avoid measurement errors caused by meter loading. I recommend the lm324 for dc and low frequency ac circuits and the tl082 for ac projects involving audio or higher frequencies.
The circuit of a relaxation oscillator must be a nonlinear one.
All oscillator circuits were built with tlv247x op amps 5 resistors and β 1 a a v v in out 20 capacitors. Hence component tolerances cause differ ences between ideal and measured values. The circuit of a relaxation oscillator must be a nonlinear one. The circuit design must also involve an energy storing device like a capacitor or inductor which charges and discharges continuously to produce a cycle.
