- This brief introduces a compensation structure for frequency response mismatch (FRM) errors in two-channel time-interleaved analog-to-digital converters (TI-ADCs) based on polynomial models of the channel frequency responses. It can be used for any Nyquist band and it comprises parallel error approximation branches (EABs), each branch consisting of a fixed differentiator of unique degree cascaded with a variable multiplier and a simple modulator. It suffices to alter the variable multipliers when the channels change, thereby avoiding online filter design. In addition, it achieves a lower latency and a significantly lower computational complexity compared to cascaded polynomial-based structures. Numerical simulations and comparisons are included, validating the efficacy of the proposed structure.
