Abstract :
A previously presented method for estimation of time errors in time-interleaved A/D converter systems is here verified on measurements from a dual A/D converter system. The advantage of this estimation method, compared to other methods, is that it does not require any knowledge about the input signal. The estimation is most accurate for slowly varying input signals but the signal quality is improved even when the estimation is done for a sinusoidal signal close to the Nyquist frequency.
