Abstract: An exemplary embodiment relates to a communication device. A communication device includes: a transmitting unit generating a first analog signal and a second analog signal based on an input signal; and a receiving unit including a first capacitor having a first terminal to which the first analog signal is input and a second capacitor having a first terminal to which the analog signal is input. The receiving unit constantly controls a reference voltage electrically coupled with a second terminal of the first capacitor and a second terminal of the second capacitor, and generating an output signal based on a result of comparison between a first pulse signal generated at the second terminal of the first capacitor and a second pulse signal generated at the second terminal of the second capacitor.
