  • Method and apparatus for clamping a high-speed digital signal delivered over a transmission line
    Patent number: 6084457
    Abstract: A clamping circuit useful in reducing ringing on a transmission line is described. The clamping circuit includes a pair of transistors coupled between the transmission line and opposite terminals of a voltage source. An enable circuit monitors the transmission line for transitions, both low-to-high and high-to-low, and enables the transistors to be biased such that they connect the transmission line to the voltage source in the presence of ringing.
