摘要：

Interleaving is one method of configuring a highspeed speed waveform digitizer. Degradation of the dynamic range, however, results from co-channel mismatched characteristics among the individual ADCs. Especially mismatches of the non-linear characteristics have not been analyzed so far. This paper constructs a mathematical model, and proposes a method for correcting mismatches of both linear and non-linear characteristics using a digital signal processing technique. This method does not require any additional hardware.
