A semiconductor device includes a plurality of first inductors having a spiral shape and provided in a modulator of a transmitting side, and a plurality of second inductors having a horseshoe shape and provided in an oscillator of a receiving side, the plurality of second inductors being arranged such that an opening of plurality of second inductors is disposed opposite to the plurality of first inductors. The semiconductor device performs a transmission process and a reception process using a radio wave.

A receiver includes a continuous-time equalizer, a decision-feedback equalizer (DFE), data and error sampling logic, and an adaptation engine. The receiver corrects for inter-symbol interference (ISI) associated with the most recent data symbol (first post cursor ISI) by establishing appropriate equalization settings for the continuous-time equalizer based upon a measure of the first-post-cursor ISI.
