Reconstruction of Non-uniformly Sampled Signal after Time-Interleaved ADCS using Transposed Farrow Structure

This paper considers the problem of correcting time-skew errors in time-interleaved analog-to-digital converter systems (TI ADC). The reconstruction of the uniform sequence and correction of the time-skew error is done by using polynomial-based interpolation filter implemented as transposed Farrow structure. The main advantages of the proposed reconstruction system are higher flexibility and reduced number of multipliers. The system is highly flexible and allows output sampling rate that is independent of the sampling rate of each subconverter of TI ADC system
