However, offset mismatch, gain mismatch, and timing error between time-interleaved channels degrade the performance of time-interleaved ADCs. This paper focuses on the gain mismatch and timing error. Techniques based on Discrete Fourier Transform (DFT) for estimating and correcting gain mismatch and timing error in an M-channel ADC are depicted. Numerical simulations are used to verify the proposed estimation and correction algorithm.}, type={Artykuły / Articles}, title={Estimation and Correction of Gain Mismatch and Timing Error in Time-Interleaved ADCs Based on DFT}, URL={http://www.czasopisma.pan.pl/Content/90270/PDF/Journal10178-VolumeXXI%20Issue3_14.pdf}, doi={10.2478/mms-2014-0045}, keywords={correction, estimation, gain mismatch, time-interleaved analog-to-digital converter, timing error}, }
