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 ...

[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, ...

CMOS ring voltage controlled oscillator with combined delay stages is presented. Initially, the general condition of oscillators is discussed then two common inverters are introduced and their delay ...
