Abstract: A switching scheme to realize 2nd-order digital-to-analog converter (DAC) mismatch error shaping (MES) technique in the high-resolution noise shaping successive approximation register analogue-to-digital converters (NS SAR ADCs) is proposed. By feeding back the combination of… read more here.

Abstract: This work presents a 14-bit oversampled successive-approximation-register (SAR) analog-to-digital converter (ADC) with mismatch error shaping (MES) and pre-comparison techniques. A pre-comparison technique is proposed to solve the over-range problem caused by MES. With MES and… read more here.
