DAC-DETR: Divide the Attention Layers and Conquer

Neural Information Processing Systems, 2023
This paper reveals a characteristic of DEtection Transformer (DETR) that negatively impacts its training efficacy, i.e. , the cross-attention and self-attention layers in DETR decoder have opposing impacts on the object queries (though both impacts are ...

Digital Background Calibration of a Split Current-Steering DAC

IEEE Transactions on Circuits and Systems I: Regular Papers, 2019
A digital background calibration method for a current-steering digital-to-analog converter (DAC) is presented. The algorithm uses one comparator for calibration and corrects for current-source mismatch, which causes DAC nonlinearity.
