wein bridge sine wave oscillator lm101

Posted on Feb 4, 2014

This circuit is Wein Bridge Sine Wave Oscillator. The main problem in producing low distortion, constant amplitude sine wave to get the right loop gain amplifier. By using the 2N3069 JFET as variable resistor in the feedback loop voltage amplifier, this can be easily achieved. LM103 zener diode provides a reference voltage to the peak amplitude si
