Abstract
A semiconductor device including a PLL providing candidate clocks of different phases in response to a first clock received from a reader via an antenna, a phase difference detector detecting a phase difference between the first clock and a clock from the candidate clocks, a phase difference controller that selects another clock from the candidate clocks, and a driver that provides transmission data synchronously with the another clock to the reader.
