Abstract: A receiving circuit includes a comparing circuit, a first storage circuit, a second storage circuit, and a voltage controlling circuit. The comparing circuit compares an input signal with a reference voltage and outputs a signal with either a first level when the input signal is larger than the reference voltage or a second level when the input signal is smaller than the reference voltage as a comparison result. The first storage circuit stores an output level of the comparing circuit for a next one cycle. The second storage circuit stores an output level of the first storage circuit for a next one cycle. The voltage controlling circuit controls a level of the reference voltage in each cycle on the basis of output levels of the first storage circuit and the second storage circuit.

Abstract: An apparatus includes a substrate which includes an electronic component mounted on the substrate, the electronic component for processing a pair of signals, the substrate including a first wire for transmitting one of the signals, the first wire being formed on a first layer of the substrate, and a second wire for transmitting another one of the signals, the second wire being formed on a second layer of the substrate in a first region under the electronic component and being formed on a third layer in a second region of an other part of the first region.
