Abstract
The possibility to identify and correct DC offset errors in time interleaved ADCs are investigated. It is shown how the offset introduced by the ADC can be identified and corrected by utilizing the knowledge about the target application. As target application the ADSL standard has been used. It is shown that an offset error from a time interleaved ADC can be handled efficiently in a wideband communication system as ADSL
