Wien bridge with asymmetrical supply
Normally, a Wien bridge oscillator contains two identical capacitors and two iden tical (variable) resistors. That being the case, the transfer factor of the bridge is 1:3. For example, when a potential of 1 V is applied to the non-inverting input of the opamp, the output voltage of the amplifier will be 3 V.
