Sine Wave Oscillator

This is a Sine Wave Oscillator circuit. This circuit as known asĀ  amplitude-stabilized sine-wave oscillator. It can gives high purity sine-wave output down to low frequencies with minimum circuit complexity. This circuit has a several advantages such as it does not use the traditional tungsten filament lamp amplitude regulator, so the problem problems associated with …
