For a favor I need to design a Wien bridge oscillator with an oscillation frequency in the range of 1.9 kHz and 2.1
kHz. Use ±15 V supplies for the opamp.
Then I find following circuit which is suppose to have f=20kHz [I try to build a proper Wien and then shift f to 2kHz with replacing RC components magnitudes.] and build it with Pspice but I can't get an output
I read that i need to connect a function generator to give ossilation a head start but I can't figure out how I am gone connect FC tor circuit ?
Also to achieve 2kHz maybe I need help but having a output has got first priority
