The Effect of Differential Driver Asymmetries on Common-Mode Frequency Spectrum

A frequency spectra determination of the common-mode signal due tothe differential driver asymmetries is presented. The analyticalexpression for the Fourier series is developed and the evaluations fordifferent dependencies are introduced. The effect of the skew time andamplitude imbalance is shown i...
