ABSTRACT:
A device for generating a pair of true/complementary-phase logic signals is provided. The device comprises a single-end to true/complementary-phase signal conversion circuit, a first stage circuit and a differential amplifier. The conversion circuit receives a single-end signal and converting the single-end signal to a first pair of true/complementary-phase signals. The first stage circuit receives the first pair of true/complementary-phase signals and performing a feedback control to obtain a second pair of true/complementary-phase signals. The differential amplifier receives the second pair of true/complementary-phase signals and outputs a pair of differential signals. Therefore, the rising time/falling time of one of the pair of differential signals is synchronized with the falling time/rising time of the other of the pair of differential signals.
