Wien Bridge Oscillator. Resistance r 3 and the lamp l p are used to stabilize the amplitude of the output. This property can be exploited to make an oscillator.
This property can be exploited to make an oscillator. The circuit construction of wien bridge oscillator can be explained as below. The bridge comprises four resistors and two capacitors the oscillator can also be viewed as a positive gain amplifier combined with a bandpass.
The phase shift between the input and the output of the network is zero at one particular frequency.
The wien bridge oscillator is developed by maxwien in the year 1981. It uses a series and a parallel rc circuit connected as a potential divider to provide frequency dependent phase shift. One of the simplest sine wave oscillators which uses a rc network in place of the conventional lc tuned tank circuit to produce a sinusoidal output waveform is called a wien bridge oscillator. Wien bridge oscillator the wien bridge oscillator can still be built using similar principles to the early hewlett packard versions but with modern components.
