A second-order noise shaping (NS) successive approximation register (SAR) analog-to-digital converter (ADC) is proposed for sensor interface applications. It consists of a capacitor-resistor hybrid digital-to-analog-converter (C-R DAC) with 10-bit resolution, a comparator with three inputs, a SAR lo...
