Testing ADCs for Static and Dynamic Nonlinearities —Killing two birds with one stone—
نویسندگان
چکیده
Traditionally, static linearity and dynamic distortion tests are performed separately for ADCs. To this end, a low-frequency sinewave is histogrammed to measure static Integral Nonlinearity, and a high-frequency sine-wave is sampled for FFT processing to measure dynamic distortions and dynamic range. We propose to use a model-based technique to extract both static and dynamic nonlinearities from a single data record of a sampled high-frequency sine-wave. This saves test time as the ADC converts fewer samples.

Analog-to-digital converter testing - new proposals
New static and dynamic analog-to-digital converter (ADC) testing techniques are revised and discussed. A new test method based on the Histogram Method but using small-amplitude triangular waves with a variable offset is shown to have several advantages over the traditional static test, namely a dramatic reduction in test duration even for highresolution ADCs. The use of Gaussian noise to stimul...

متن کاملCorrelation Between Static and Dynamic Parameters of A-to-D Converters: In the View of a Unique Test Procedure
ADCs are fully characterized by both static and dynamic parameters. Testing methods usually combine a histogram-based approach with a spectral analysis to determine the complete set of ADCs parameters. In the view of a unique test procedure, this paper investigates the correlation between both kinds of parameters. Experimental results demonstrate that under appropriate test conditions, the dyna...
