Abstract
A receiver that receives a multi-level signal includes a compensation circuit, a sampling circuit, an output circuit and a mode selector. The compensation circuit generates a plurality of data signals and a plurality of reference voltages by compensating intersymbol interference on an input data signal. The sampling circuit generates a plurality of sample signals based on the plurality of data signals and the plurality of reference voltages. The output circuit generates output data based on the plurality of sample signals, and selects a current value of the output data based on a previous value of the output data. The mode selector generates a mode selection signal used to select one of first and second operation modes based on an operating environment. The compensation circuit and the sampling circuit are entirely enabled in the first operation mode, and the compensation circuit and the sampling circuit are partially enabled in the second operation mode.
