Main Objective: The main goal of this research project is the advancement of the knowledge in the area of analogue to digital converter testing. We propose the pursuit of the following objectives: a) Study of the precision of Independently based Gain and Offset Error; b) Development of a Weighted Least Squares Estimator for gain and offset error estimation; c) Study of the influence of additive noise in the bias of ADC gain and offset error estimation; d) Study of the use of sinusoidal stimulus signals instead of triangular stimulus signal as suggested in the IEEE 1057-94 standard procedure for ADC random noise estimation; e) Derivation of an exact estimator for ADC random noise estimation; f) Study of the influence of sinusoidal amplitude and offset on the bias and precision of the estimation of the fitted sine wave parameters; g) Derivation of an expression for the minimum number of samples required to achieve a given upper bound on the estimation bias and precision; h) Study of the precision of novel sine-fitting algorithms used in impedance measurement. |
