Hello everyone, I am having trouble getting this simulation to work. I am a complete novice at LTSpice, i have to design a Wien bridge oscillator in LTSpice. The gain of the amplifier should be automatically adjusted by using a FET.
I taught I can do that but it seems I was wrong. I have simulated the circuit but the output does not oscillate, see below, I attached a snap of the circuit and the .asc file.
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 add the FET it just doesn't work.
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.
