A 108dB SNR 1.1mW Oversampling Audio DAC with a Three-Level DEM Technique

Previously reported multi-bit oversampling DeltaSigma audio DACs use 2-level (+1, -1) unit elements in either switched-capacitor or current-steering form. This paper presents a low-power audio DAC that uses a 3-level current-steering unit element architecture.
