Squeeze 10-Bit Performance From An 8-Bit ADC, Part 2: Triangular Dithering

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 ...

Increasing ADC resolution by adding dither to DC signals

An EDN Design Idea (DI) presented a discussion of how to increase the resolution of an ADC by adding a non-deterministic, zero-mean, Gaussian noise dither waveform to a signal to be converted; then, ...

Squeeze 10-Bit Performance From An 8-Bit ADC, Part 3: Self-Dithering ADCs

If the input signal moves at least the analog-to-digital converter’s (ADC’s) resolution (Δ) over the time it takes to take multiple samples, the average result of these multiple signals will increase ...
