Sine-fitting by the energy-based method in the dynamic testing of ADCs

The paper proposes a sine-fit algorithm exploiting the Energy-Based Method (EBM) to estimate the sine-wave parameters. Its use in the estimation of Analog-to-Digital Converter (ADC) spectral parameters like SIgnal-to-Noise And Distortion (SINAD) ratio and Effective Number Of Bits (ENOB) is investigated. A performance comparison with some state-of-the-art ADC test methods is performed using both computer simulations and experimental results. Finally, some important results concerning the algorithm design process, such as the selection of the optimal window and the number of acquired samples, are reported.
