    Abstract: A receiver receiving a multi-level signal includes a sample and hold circuit, first and second analog-to-digital converting circuits, and a digital-to-analog converting circuit. The sample and hold circuit generates a sample data signal by sampling and holding an input data signal. The first analog-to-digital converting circuit generates a first bit of output data based on the input data signal and a first selection reference voltage among a plurality of reference voltages. The digital-to-analog converting circuit selects at least one additional selection reference voltage from among the plurality of reference voltages based on the first bit of the output data. The second analog-to-digital converting circuit generates at least one additional bit of the output data based on the sample data signal and the at least one additional selection reference voltage.
