dc.description.abstract This paper presents a dynamic element matching (DEM) decoder incorporating both intersymbol interference (ISI) and mismatch error shaping. From the analysis of ISI error in multi-bit DACs, an algorithm is developed that deterministically controls the element transitions, such that on each conversion cycle the instantaneous number of on transitions is set to a constant value, while the instantaneous number of off transitions varies with the decoder input signal. The technique achieves greater ISI error mitigation than previous approaches using less hardware. To further reduce the logic area, a hierarchical DEM structure, whereby the DEM decoder is split into multiple sub-DEM decoders, is presented. en_US
