Abstract: A decision feedback equalizer including: a first input latch configured to generate a first output signal from first data received by the first input latch, wherein the first input latch includes: a first sub-circuit configured to receive the first data and a reference voltage, compare the first data and the reference voltage, and generate first internal signals having different transition timings according to a result of the comparison between the first data and the reference voltage; and a second sub-circuit configured to receive, as first feedback, a second output signal, which corresponds to second data received by the first latch earlier than the first data, and generate the first output signal, which compensates for a difference between the transition timings of the first internal signals, based on the first feedback.

Abstract: A calibration device includes a first comparator that outputs a first result of comparing a level of a first voltage of a first node and a level of a reference voltage, a second comparator that outputs a second result of comparing the level of the first voltage and a level of a second voltage of a second node, and a control signal generator that outputs a first signal for adjusting a first resistance value of a first resistor circuit based on the first result and to output a second signal for adjusting a second resistance value of a second resistor circuit based on the second result. The first node is between the first resistor circuit and a reference resistor, and the second node is between the second resistor circuit and a third resistor circuit which is adjusted to have the same resistance value as the first resistance value.

Abstract: A method of calibrating a clock phase and a voltage offset includes receiving an input data signal that is periodically toggled. A clock phase calibration operation is performed based on an up signal and a down signal, such that phases of a plurality of clock signals are adjusted. The up signal and the down signal are generated based on the input data signal, a reference voltage and the plurality of clock signals. A voltage offset calibration operation is performed based on the up signal, the down signal and a first sample data signal, such that a voltage level of the reference voltage is adjusted. The first sample data signal is generated by sampling the input data signal based on one of the plurality of clock signals. The clock phase calibration operation and the voltage offset calibration operation are performed independently of each other and not to overlap with each other.
