Abstract

A receiver circuit includes an input unit configured to receive a reception pattern signal in a training mode, and a reception normal signal in a normal mode, an enable control unit configured to determine whether to activate an enable signal according to the reception pattern signal in the training mode, a first decision feedback equalizer configured to operate in an activation period of the enable signal, and to remove a first post-cursor component for the reception normal signal by calibrating a currently received value based on a previously received value of the reception normal signal, and a second decision feedback equalizer configured to, when the enable signal is in an activated state, remove second to Npost-cursor components for the reception normal signal by adjusting driving abilities of input transistors, to which the currently received value is applied, according to patterns of the reception normal signal.
