Signal buffer for high-speed signal transmission and signal line driving circuit including the same

摘要

A signal line driving circuit includes an inversion buffer, a pulse generator, a first signal buffer, and a second signal buffer. Here, the inversion buffer receives an input signal and includes an output terminal connected to the signal line to drive the signal line. The pulse generator receives the input signal to generate a pulse signal. The first signal buffer has a control terminal connected to an output terminal of the pulse generator and an input/output terminal connected to a node of the signal line. The first signal buffer reduces the rising transition time of a signal propagating on the signal line in response to a first control signal. The second signal buffer has a control terminal connected to the output terminal of the pulse generator and an input/output terminal connected to the node of the signal line. The second signal buffer reduces the falling transition time of a signal propagating on the signal line in response to a first control signal.
