Abstract :
The paper deals with the uncertainty evaluation for the most used figures of merit of analog to digital converters in technical standards. Total Harmonic Distortion (THD), Spurious-Free Dynamic Range (SFDR), Signal to-Noise And Distortion ratio (SINAD) and Signal to Noise Ratio (SNR), as defined in IEEE Std.1057, have been considered in order to derive practical uncertainty propagation formulas. The proposed formulas have been validated on simulated and actual signals.
