Abstract
A method for the compensation of frequency-response mismatch errors in M-channel time-interleaved ADCs. The compensation is done utilizing a technique that makes use of a number of fixed filters, that approximate differentiators of different orders, and a few variable multipliers that directly correspond to parameters in polynomial models of the M channel frequency responses. A compensated M-channel time-interleaved ADC is based on and can perform the method.
