Wien-Bridge Sine-Wave Oscillator

Posted on February 7, 2011 by Rend

This is a Wien-bridge sine-wave oscillator circuit. This circuit uses negative-feedback stabilization to make sure the gain won’t go higher than unity to prevent signal distortion. The D2 and D1 will conduct when Negative peaks in excess of -8.5 V. … Continue reading →
