Abstract :
A test methodology for linear modeling of subranging analog-to-digital converters with digital correction is proposed. A reduced physical model of integral nonlinearity errors is obtained by the application of the ambiguity algorithm. Simulation results are provided which demonstrate that a sensible reduction of the number of test points can be obtained, thus reducing the high costs of testing, with low prediction errors
