This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over ...

If you use a function generator, you may occasionally require a sine-wave output at a higher frequency than the generator can provide. If your function generator also produces a triangle-wave output, ...

Part 1 of this column (ED Online 18899) showed how designers can use additive dither and oversampling to increase the resolution of an analog-to-digital converter (ADC). In this edition, we will ...
