Hi, I am trying to build Wien-Bridge oscillator in PSpice and I want to produce sine wave. The circuit seems to be correct but when I do tansient analysis the output is not produced. What should I do?

Step 1: Be sure that you have given the input and output variables on the circuit correctly.

Step 2:after giving variables names click the option to display the net name on the circuit. You can also select the color for your waveform of the signal you want to be displayed in transient analysis.

Step 3:Go to simulation settings. Transients-->give run to time based on the input you have given. Also give maximum step size.

Step 4: go to options - - > analog simulation>auto converge and then click OK.

Step 5: Go to data collection and make sure power voltage current and noise options are selected as All. Then click OK.

Step 6:go to probe window and make sure display probe window option is selected and click OK.

Final step is to place probes at the input and output variables and right click on them and click on end mode. Now run the simulation and you'll get your transient response.

If the above things don't work, then it is possible that you have

1.made connections wrong

2.made junctions which aren't necessary

3.not placing ground to the circuit.

Try above things and you'll definitely get a result.

Hope this helps.
