Abstract: A digital background calibration technique for pipelined successive approximation register (SAR) analogue-to-digital converters (ADCs) with detect-and-switching (DAS) algorithm is proposed. The DAS algorithm exploits basic combinational logic to detect the first-stage conversion results, thereby determining…

Abstract: This work presents a single-channel, fully dynamic pipelined-SAR ADC with relaxed architectural tradeoffs thanks to the use of ring amplification and background calibration. It leverages a novel SAR quantizer and narrowband dither injection to achieve…

Abstract: 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. The DAC is split into two…
