Transmitter/receiver for supporting differential signaling and semiconductor transmitter/receiver system including the same

摘要

A transmitter includes first to third power supply terminals, a first buffer that is electrically coupled between the first power supply terminal and the second power supply terminal and buffers and outputs a first input signal, and a second buffer that is electrically coupled between the second power supply terminal and the third power supply terminal and buffers and outputs a second input signal that is in a differential relation to the first input signal.

1. A transmitter comprising:
first to third power supply terminals; a first buffer that is electrically coupled between the first power supply terminal and the second power supply terminal, buffers a first input signal and outputs a first transmission signal; and a second buffer that is electrically coupled between the second power supply terminal and the third power supply terminal, buffers a second input signal that is in a differential relation to the first input signal and outputs a second transmission signal that is in a differential relation to the first transmission signal, wherein the first and second transmission signals swing spaced apart from each other about a voltage level of the second power supply terminal, and wherein the voltage level of the second power supply terminal has an intermediate voltage level between voltage levels of the first power supply terminal and the third power supply terminal.
