An Improved Methodology for Sample-Time Calibration in Time-Interleaved Analog-to-Digital Data Converters
2016
Bulletin de la Société royale des sciences de Liège
Preserved Fulltext
A mixed-signal scheme is presented for the sample-time error calibration in time-interleaved analog-to-digital converters (TIADC). Interchannel equalization is used to remove the sample-time error mismatch between channels using an extra channel. Simulation results show that the proposed technique is able to improve the SNDR for a 12-bit TIADC system by 29 dB at 37% of the Nyquist rate frequency.
