## Abstract

A circuit device includes a positive phase signal line, a negative phase signal line and a single-ended signal line. The positive phase signal line includes a first positive-phase-signal-line terminal and a second positive-phase-signal-line terminal for transmitting a first signal. The negative phase signal line includes a first negative-phase-signal-line terminal and a second negative-phase-signal-line terminal for transmitting a second signal. The single-ended signal line is disposed between the positive phase signal line and the negative phase signal line, and includes a first single-ended signal line terminal and a second single-ended signal line terminal for transmitting a single-ended signal. The first signal of the positive phase signal line causes a first noise on the single-ended signal line. The second signal of the negative phase signal line causes a second noise on the single-ended signal line. The first noise and the second noise eliminate one another.
