Abstract
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.
