The time-interleaved ADC structure is one way to increase the sampling rate. However, channel mismatch errors of this structure will increasingly degrade the performance of the whole system. For this reason, adding test signal is widely used when measuring and calibrating the mismatch errors. This paper propose a method which measure mismatches without the need of any special calibration signal and therefore has wide applications. Furthermore, the method of error estimation of blind algorithm is improved. The computer simulations show that the method estimates errors with high accuracy and can improve the performance of the system effectively.
