For my assignment, I was required to model an Op-Amp using a Behavioral Voltage Source using LTSpice.
The input resistance of the Op-Amp is 70MΩ and output resistance is 30Ω. The open loop voltage gain is 80k and the supply voltages is +-15V. I'm having problems with the behavioral voltage source. This is what I got so far.
Can anyone help me? Thank you in advance.
I need help again. I am supposed to use the above op-amp model to create a non-inverting amplifier with a gain of 40.
This is what I have now. But the syntax for the behavioural voltage source does not work. What does it need to be?
Edit: Ive figured it out, changed it to "V=limit((V(Vi)-V(Vx))*80k,-15,15)" and it worked.
