Generalized Quadrature Data Weighted Averaging

This brief focuses on quadrature multibit digital-to-analog conversion with data weighted averaging (DWA) as a linearization method. Previous study on generalized DWA is expanded here, into the complex domain, and is compared with prior art on complex DWA. It will be shown that the generalized DWA in the complex domain has several advantages such as reduced complexity, reduced spurious behavior, and inherent quadrature error suppression.
