Experimental Comparison of Different Standards for Dynamic Characterization of ADCs

This paper reports the first results of an experimental comparison of the test procedures described in the IEC and IEEE standards for the measurement of the analog-digital converter (ADC) dynamic performance in the frequency domain. The comparison has been carried out by setting up the standard test benches and applying the standard test procedures for measuring the spurious free dynamic range (SFDR), total harmonic distortion (THD), signal-to-noise-and-distortion ratio (SINAD), signal-to-noise ratio (SNR), and effective number of bits (ENOBs) of the three actual ADCs. The achieved results show a good degree of harmonization, even if the procedures and formulas are different.
