Abstract:

Linearity and spectral performance test contributes most cost of ADC test. This paper presents a new method for testing an ADC's SNR from its linearity test data. The method does not require additional data acquisition or accurate sinusoidal stimulus. Data collected for linearity test is used to compute the input noise power and test ADC's SNR. Both simulation and experimental results show that the proposed method can estimate SNR value accurately.
