Hi all, I am having trouble getting this simulation to work. I am a complete novice at LTSpice but the question seemed simple enough, simulate Wien bridge in LTSpice and printout the transient response.
I can do that I thought but it seems not. I have simulated the circuit but the output does not oscillate it just sits at 11V see below, top is the circuit from the course work, then my circuit and output.
I have tried a couple of other wien bridge circuits of the web, some shown in LTSpice and shown with an output chart but when I copy them I just get a flat line output.
Can any one give me a pointer as to what I am missing how do you make an oscillator oscillate?
Thanks for any advice you can offer.
