A Wien bridge oscillator is a type of electronic oscillator that generates sine waves. It can generate a large range of frequencies . The oscillator is based on a bridge circuit originally developed by Max Wien in 1891 for the measurement of impedances . [ 1 ]
The Wien bridge is a type of bridge circuit that was developed by Max Wien in 1891. [1] The bridge consists of four resistors and two capacitors . At the time of the Wien bridge's invention, bridge circuits were a common way of measuring component values by comparing them to known values.
It was a low-distortion audio oscillator used for testing sound equipment. It used the Wien bridge oscillator circuit, that had been the subject of Bill Hewlett's masters thesis. It was also the first such commercial oscillator to use a simple light bulb as the temperature-dependent resistor in its feedback network. [2]

A voltage-controlled crystal oscillator (VCXO) is used for fine adjustment of the operating frequency. The frequency of a voltage-controlled crystal oscillator can be varied a few tens of parts per million (ppm) over a control voltage range of typically 0 to 3 volts, because the high Q factor of the crystals allows frequency control over only a ...
