Amplitude-stable oscillator has low distortion, low cost

Posted on Apr 10, 2012

The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a). When the output is positive, the positive input terminal equals ½V+, and the voltage at the negative input terminal changes toward V+. When this voltage exceeds ½V+, the output voltage rapidly changes to V. The positive input terminal becomes ½V, and the negative input terminal changes toward V.
