Test Frequency-Domain Parameters of ADCs Using a Spectrum Leakage Correction Algorithm
This paper analyzed the principle of the interpolation algorithm and the cause of spectrum leakage, derived an interpolation formulas of estimation the incoherent degree to correct the spectrum. Polynomial approximation method is used to get the correction formulas. Simulate results demonstrate that the correction Algorithm can reduced the spectral leakage and increase ADC parameters calculation accuracy.
