Build a Simple Voltage-Controlled Oscillator (VCO) with CD4046 | DIY Synth Circuit Tutorial

In this video, we’ll build a simple Voltage-Controlled Oscillator (VCO) using just one IC — the CD4046 Phase-Locked Loop. I’ll walk you through every connection, from the capacitor between pins 6 and 7 to setting your minimum and maximum frequency range with resistors on pins 11 and 12. You’ll also learn how to drive the circuit with a simple voltage divider to modulate the output frequency from 0 to 9 V. This circuit is perfect if you’re working on an audio sequencer or a DIY synthesizer project — especially when paired with a CD4017 counter for step sequencing. 🔧 Parts Used: CD4046 PLL IC 0.47 µF capacitor (pins 6-7) 470 Ω resistor (pin 11 → GND) 1 MΩ resistor (pin 12 → GND) 9 V power supply Potentiometer (for voltage control) Output jack → small amp or speaker 🎶 What You’ll Learn: How a VCO works using voltage input control How to tune frequency range with resistors and capacitors How to connect the CD4046 for sound experiments or sequencers Don’t miss the next video where I’ll connect this VCO to a CD4017 sequencer to create an analog audio step-sequencer! 👉 Subscribe to The Phil Studio for more DIY synth circuits, audio electronics, and experimental sound projects.
