CMOS hex inverter generates low-distortion sine waves

Posted on Jan 6, 2013

This Design Idea provides a simple, inexpensive, portable circuit as an alternative to a microcontroller to provide a wide-range source of low-distortion sine waves for audio-circuit design and debugging. Although sine waves from DDS (direct digital synthesis) offer greater stability and fewer harmonics and other spurious-frequency components, this more `retro` approach lets designers use Linear Technology Corp`s LTSpice freeware and hone their circuit-simulation skills.
