In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of ...

It works with a supply voltage of 1.2V and features 5% frequency ... is shifted from lvdd to vdd. Fig. 1 - Ring oscillator block diagram. The frequency behavior of such current-controlled ring ...
