Parametric spectral analysis tools for the characterization of A/D converters

Abstract

This paper focuses on the estimation problem of typical parameters of the A/D converters. As basic assumption, the data output consists of a sum of real sinusoids. In this framework, we investigate the interest of the parametric spectral methods in the ADC testing. We give the detail of the three major estimation steps in order to retrieve all signal output parameters. Finally, we present the major advantage of this estimation scheme: the good results obtained in spite of the noncoherent frequency feature used in the test.
