Build a Wien bridge oscillator that oscillates at 2. 1kHz and that can be switched on by a transistor. The reason for me placing a transistor switch in the circuit is so that I can turn the oscillator on and off from a PIC MCU. However, when I build the simulation in multisim, I get an DC output voltage of 3. 0mV and an. I want an output voltage of 5. 0V p-p, so can anybody explain to me what
the problem with this circuit is Any help would be much appreciated.
