Abstract

Current and emerging applications need high speed and high resolution analog to digital converters (ADCs). Direct conversion for radar, communications, measurement systems as well as lower speed higher resolution applications such as medical imaging could benefit from the use of time interleaved analog to digital converters (TIADCs). This paper presents the implementation and results of the proposed adaptive linear combination of non-linear filters for post conversion correction of TIADCs applied to a behavioral TIADC model. Results show that the channelized correction scheme can suppress linear and nonlinear mismatch spurs by a significant amount, 30dB in the 2TIADC case, without the need for known system parameters.
