Calculate the Effective Number of Bits of an ADC

You are considering using the AD9643 14 bit ADC in your next design. The datasheet specifies SINAD (signal-to-noise and distortion) for multiple input frequencies. You plan to sample a 220 MHz signal ...

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, ...

Using input-referred noise to improve analog-to-digital converter resolution

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...
