Welcome to part one of a series taking you down the rabbit hole of DIY electronic synthesizers based on (largely) CMOS logic chips. Instead of synths being commodity gear made by large corporate ...

This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

A crystal oscillator is a timing device that consists of a crystal and an oscillator circuit, providing an output waveform at a specific frequency. When a crystal is placed into an amplifier circuit ...

Today we’ll take a journey into less noisy noise, and leave behind the comfortable digital world that we’ve been living in. The payoff? Smoother sounds, because today we start our trip into analog. If ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...
