Abstract
An improved code density test for flash A/D converters is proposed, re vealing some dynamic phenomena (e.g., missing codes) hidden by the con ventional approach. Formulas are reported for obtaining, from code den sity, effective noise estimates fully consistent with those provided b y waveform analysis. Finally, it is shown that the variance of noise e stimates obtained by time-domain analysis may be unacceptably large if the observation window is not properly chosen.
