An output terminal of the emitter follower serves as an output terminal of the equalization circuit.

Abstract: A balancing circuit which may compensate for bandwidth attenuation introduced by interference between signals includes an amplifying circuit, a rising edge detection circuit and/or a falling edge detection circuit. By means of detecting the rising/falling edge of an original signal, the resulting pulse signal contains the phase information of a single “0” bit and a single “1” bit in the original signal, thus the phase of a rising edge or the phase of a falling edge of the original signal may be compensated respectively, so as to compensate for the high-frequency attenuation caused by interference between signals.
