I'm new to PSpice and here I was trying to simulate a square wave oscillator using a LM193 on PSpice. Here is the circuit that I've created there:
Edit: The capacitor C1 has an IC set to 0
However, when I plot the waveform of Vout, this is the obtained result:
Even though this form "resembles" a square wave, it's not even close to what I wanted. I'd be really thankful if someone could explain a couple of things to me:
Why is the signal oscillating only between 0 and -5V? Shouldn't it be between -Vsat and + Vsat, where Vsat is used to designate the saturation voltage of the Op Amp? What have I done wrong in this circuit?
Moreover, isn't the output voltage supposed to be more symmetrical (therefore resembling more a square wave)? If someone could give me some advice on how to make it more like it I'd appreciate it.
Thanks a lot for your attention!
