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 ...

More undocumented applications for the 555 ‘oscillator:’ Not all applications oscillate as we will see. Most are knowledgeable about common CMOS logic inverters and Schmitt triggers such as the 74HC04 ...

The miniature 74AUP2G family of advanced ultra-low power CMOS logic devices include seven versions of dual inverters and buffers. The chips use a 0.8 to 3.6 V supply, have ±4 mA output drive at 3 V, ...

[Dr. Shane] asks the question: what happens if you connect the output of an inverter logic gate back to the input? In theory, it doesn’t make sense, but depending on the gate’s physical construction, ...

Transistor is a solid state, three terminal semiconductor amplifying device. Transistor is the fundamental component of most electronic circuits. Bipolar, and Field Effect Transistor (FET) are two ...
