PURPOSE: An active hybrid circuit for high-speed wire communication is provided to prevent data transmitted from a transmitter from being reflected to a receiver, thereby reducing an influence of a reflected wave and reducing signal attenuation. CONSTITUTION: The first digital to analog converter(10) converts a digital signal into an analog current signal, and performs an impedance matching. The second digital to analog converter(20) is applied with the same signals as the digital signal of the first digital to analog converter(10), and generates the same output value as the first digital to analog converter(10). A signal converter(30) converts the current signal of the first digital to analog converter(10) into a voltage signal, and transmits data. A differential amplifier(40) is applied with output values of the first and the second digital to analog converters(10,20), and removes an influence of a reflected wave of the signal converter(30).
