N2 - A deterministic description of bandwidth-interleaved (BI) system with offset, gain and time mismatches among subADCs is firstly developed in this paper. Based on the analysis, spurious spectra caused by gain and time mismatches are correlated with the input signal, while spurious spectra caused by offset mismatch are independent with the input signal but related to the frequency of the local oscillator in each subband. The analysed results can be used as a reference for calibration of mismatch errors among the subbands in BI systems.
