Wien bridge oscillator circuit


Posted on Feb 7, 2014

In this laboratory experiment, we need to design the frequency determining network for a 1k Hz sinusoidal oscillator. Therefore, we should set: Capacitance = 100nF Resistance = 1520 ohm

Output voltage waveform of oscillator with varying the value of R1:

Set R1 = 2033 ohm  (The loop gain is about to 1, sustained oscillation is resulted.)

Ser R1=2.1k ohm (The loop gain is greater than 1, overdamping oscillation is resulted.)

Set R1= 1.9k ohm (The loop gain is smaller than 1, underdamping oscillation is resulted.)
