Abstract: The invention to mismatch and ISI shaping in a data converter. The invention provides a dynamic element matching technique that incorporates both mismatch and inter symbol interference shaping. A digital decoder is provided that controls the number of ‘on’ and ‘off’ transitions so that the resulting signal does not contain noise or distortion. The element selection technique of the invention is suitable for high resolution multi-bit continuous time oversampling data converters.

Abstract: A system, computer product and method are provided for providing business travel and expense benchmarking analysis. A first data storage receives and stores travel data for peer entities. A second data storage receives and stores expense transaction data for the plurality of peer entities. A data storage server aggregates the metrics of the travel data and the expense transaction data of the plurality of peer entities, generating aggregated travel and expense data. A processor compares a travel and/or expense transaction metric of an individual entity to a corresponding metric of the aggregated travel data and expense transaction data and a communications interface electronically communicates the result of the comparison to a client host computer.
