This brief presents a 2-bit/cycle successive approximation register (SAR) analog-to-digital converter (ADC) with time-domain quantization, which only needs one capacitive digital-to-analog converter (DAC) array. A duplicated dynamic comparator is adopted to generate the time references. To quantize...
