Abstract:
Clock circuitry on an integrated circuit (IC) chip, the clock circuitry being adapted to be responsive to a clock wave source, the clock circuitry comprising:a driver having an output for deriving an output clock wave in response to the clock wave of the clock wave source; a clock line having a first end coupled to said output of said driver; a receiver having an input coupled to a second end of said clock line, said receiver having a resistive input impedance causing said clock line carrying said output clock wave to said input to present to said driver output an impedance having a resistance-capacitance time constant that is a relatively small fraction of a period of the clock wave, said clock line having capacitive and inductive reactances tending to cause oscillations on the clock line in response to clock wave transitions, said resistive input impedance of said receiver having a magnitude to substantially dampen said oscillations.
