N2 - Bandwidth Mismatch between channels sampling circuits in a time-interleaved analog-to-digital data converter (TI ADC) causes undesirable distortions in the output spectrum. This error interferes in gain and phase with the static gain and clock skew errors respectively, which makes its extraction much difficult. In this paper, an online extraction technique of the bandwidth mismatch error is proposed. Furthermore, a correction solution is presented to validate this extraction.
