Status: Built
My voltage controlled oscillator is based on Mortiz Klein’s designs for a VCO combined with the saw wave to triangle wave converter that he uses as part of his wavefolder.
The core of the oscillator is based around a 40106 Schmidt Trigger Inverter. Linear to exponential conversion of the control voltage is performed by a BC548 transistor. The oscillator has an FM input which is attenuated by a potentiometer on the face plate to add some noise, and the width of the pulse output is also voltage controlled and adjustable with a potentiometer.
Future Improvements
- If I redesign this VCO, I would like to add a sine converter to get sine wave output from the module.
