ABSTRACT:
A method for statistically calibrating an analog-to-digital converter with an electronic test system. A digital-to-analog converter which has been calibrated by premeasured weighting coefficients with respect to two-state orthogonal signals is excited with two state signals at each input bit which together represent a single signal with uniform amplitude probability with respect to time, and wherein each excitation signal is orthogonal with respect to all other excitation signals. The output of the digital-to-analog converter is detected by the analog-to-digital converter under test. The digital time domain output signals are then mapped into a transform domain to obtain weighting coefficients of each bit of the output response. Finally the transform domain weighting coefficients are weighted by the reciprocal of the premeasured weighting coefficients to obtain the unbiased weight of each bit of the analog-to-digital converter under test. A preferred set of excitation signals is a set of Walsh function signals representing the digital equivalent of a linear ramp function.
