Abstract :
The estimation of mismatch-induced errors between the channels of a Time-Interleaved ADC is crucial for implementing an efficient calibration method. This step is often done with the assumption that all the noise sources have a white gaussian distribution. In this paper we analyze the statistical properties of noise components in wideband ADCs in terms of Probability Density Function (PDF) and Power Spectral Density (PSD) and discuss some conditions of whiteness.
