Measurement Verification of Estimation Method for Time Errors in a Time-interleaved A/D Converter System

• A previously presented method for estimation of time errors in time-interleaved A/D converter systems is here veried on measurements from a dual A/D converters 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 estimationis done for a sinusoidal signal close to the Nyquist frequency.
