When working with mixed-signal technology, you will find that the subject of dithering keeps showing up. Most engineers know that averaging “n” samples of an analog-to-digital converter (ADC) will ...

Since the late 1970s, designers have successfully improved the effective resolution and spurious performance of A/D converters by adding dither—uncorrelated noise—to a converter's input and then using ...

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 ...

In off-line ac-to-dc converter dithering, the pulse width modulator (PWM) frequency has proven to reduce average EMI by changing it from narrowband to broadband. This article covers a novel technique ...
