HEX oscillator
Hex inverter oscillator Today I dipped my toes into the world of analog synth and created my first oscillator. I based my design on a hex schmitt-trigger inverter chip, more precise the CD40106BE. I just picked up some components that I had laying around and created the following circuit: This seemed to produce some decent frequency range that could be usable for music (130 Hz to ~3 kHz). However when reaching the “end” of the potentiometer it seems like the capacitor is too large and makes the charge time long enough that the signal becomes a triangle wave instead of a square wave....
