Question
If the Wein Bridge Oscillator based on op-amp is tuned at 1KHz, what is the op-amp gain?
Solution 1
The gain of an operational amplifier (op-amp) in a Wien Bridge Oscillator is not dependent on the frequency it is tuned to. The gain of the op-amp in a Wien Bridge Oscillator is typically set to 3. This is because the circuit requires a gain of 3 to sustain oscillations. Therefore, even if the oscillator is tuned to 1kHz, the op-amp gain would still be 3.
