The paper illustrates a method for simultaneous ADC and DAC linearity testing in a loopback scheme. The main features of the method are: (i) it is statistically nearly optimal, being based on a maximum likelihood estimator; (ii) it does not require prior knowledge neither of the ADC nonlinearity, nor of the DAC nonlinearity - both are simultaneously measured relying only on a constant-variance noise. The performances of the method are studied both mathematically and via computer simulations. The method, because of its optimality and universality, appears to be also a good candidate for inclusion in technical standards relevant to ADC and DAC testing.

Abstract
The paper illustrates a method for simultaneous ADC and DAC linearity testing in a loopback scheme. The main features of the method are: (i) it is statistically nearly optimal, being based on a maximum likelihood estimator; (ii) it does not require prior knowledge neither of the ADC nonlinearity, nor of the DAC nonlinearity - both are simultaneously measured relying only on a constant-variance noise. The performances of the method are studied both mathematically and via computer simulations. The method, because of its optimality and universality, appears to be also a good candidate for inclusion in technical standards relevant to ADC and DAC testing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
