Measure and Calibration of Time Error in Parallel ADC
The parallel time-interleaved ADC is an effective method to improve sample-rate. However, channel mismatches lead to nonuniform sampling and degrades the performance of the whole ADC system. After analyzing the signal spectrums, this paper proposed a method to measure and verify the time-skew errors. The experiment results show that the method can calibrate the spectrums effectively.
