Identification of Unified ADC Error Model by Triangular Testing Signal

摘要

Modelling of the integral nonlinearity by the unified behavioural error model expressed as one dimensional image in the code k domain requires a minimal number of the error parameters. The unified error model consists of low and high code frequency components. This paper presents a new approach how to determine the parameters of the low code frequency component by the same signal, that was proposed earlier for determining the high code frequency component. The authors prove that the triangular testing signal with exact DC component allows determining the model parameters with a sufficient accuracy.
