Wein bridge Oscillator Circuit and Design using Op amp

wien bridge oscillator

A Wien bridge oscillator is based on bridge circuit basically used to generate sine waves at a large range of frequencies. It is a two stage RC coupled amplifier circuit that has low distortion and good stability at its resonant frequency. In our previous articles, we explain LC oscillators i.e. Hartley and Colpitts oscillator and crystal oscillator in detail. Here we are going to explain Wien Bridge oscillator and its circuit in detail. For the measurement of impedances, it was developed by Max Wien in 1891. It is one of the most demandable Oscillator use in audio or sub audio Read More …
