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.

Keywords : mixed-signal calibration, pipeline A/D converter, time-Interleaved ADC
