Creating and sharing knowledge for telecommunications

Project: InADC-In depth analysis of analog to digital converter methods

Acronym: InADC
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.
