Abstract: A data receiving device may include a dummy stage block. The dummy stage block may include m dummy stages, wherein m is a natural number greater than or equal to two. Each of the m dummy stages may be configured to remove inter-symbol interference (ISI) from a dummy input signal using dummy coefficient information to generate a dummy output signal free of the ISI. Each of the m dummy stages may be further configured to output the dummy output signal. A normal stage block may include n normal stages, wherein n is a natural number greater than or equal to two. Each of the n normal stages may be configured to remove ISI from an input signal using coefficient information to generate an output signal free of the ISI and may be further configured to output the output signal.

Abstract: A semiconductor device including an error amplifier configured to receive a voltage of an output node and a reference voltage, a flipped voltage follower (FVF) circuit configured to receive an output of the error amplifier and maintain the voltage of the output node at the reference voltage, and a bias current control circuit configured to receive first to third mode signals, control a magnitude of a bias current flowing through the FVF circuit based on the first to third mode signals, control the bias current of a first magnitude, based on the first mode signal, control the bias current of a second magnitude smaller than the first magnitude, based on the second mode signal, and control the bias current of a third magnitude smaller than the second magnitude, based on the third mode signal.
