How is it possible to control the output signal amplitude for op-amp

[Toroid]

How is it possible to control the output signal amplitude (Vout) for any particular waveform generator so
as to satisfy a particular designing criterion ?
I am referring to waveform generators using op amp 741 like
->ex.square wave generator using astable multivibrator
->the output voltage jumps from +Vsat to -Vsat how can i make it to something else that I want.

The gain of an opamp circuit is usually controlled using resistors and a feedback loop.

Show us a diagram of your circuit for further duscussion.

 

[Toroid]

The output voltage jumps from +Vsat to -Vsat as shown in the waveform

 

[Harald Kapp]

It is supposed to do that, that is the operating principle of this oscillator. If you want another amplitude, you need to scale down the output by e.g. a resistive divider.

 

[Toroid]

Can we decrease the supply voltage?
ie. +Vcc and -Vee (since saturation voltage depends on the supply voltage)

 

[Harald Kapp]

Yes you can. As long as the supply voltage meets the operating range of the opamp.
