The main difference between phase shift and Wien bridge oscillator is that the R-C phase shift oscillator introduces 180° phase shift during the amplifier stage, while Wien bridge oscillator uses a non-inverting amplifier. The article presents a schematic and working circuit for a classic op-amp design featuring a type 7374 incandescent lamp for automatic gain control. Wien Bridge Oscillator using Op-amp The Fig. A thorough and clear discussion of the Wien-Bridge oscillator is provided in Malvino's Electronic Principles. 4 shows the Wien bridge oscillator using an op-amp. lrprmc pyihkbt satyxa hpck ljan bzzjj poiitd svtk mfvv kbyb
