Estimation of A/D Converter Nonlinearities from Complex Spectrum
Jean-Marie Janik
Abstract:
The purpose of this paper is to provide a new method, which permits to estimate the integral nonlinearities of an A/D converter. This estimation uses the complex spectrum of a digitized sine wave, combined with a Fourier series expansion of the A/D converter integral nonlinearities. Thank s to this approach, an accurate estimation is obtained using fewer data than a classical method.
