Abstract
A system for synchronizing circuit operation within an integrated circuit having a high frequency clock is disclosed. The system includes an oscillator for providing a clock signal, and a clock signal complement. A two conductor transmission line is utilized to distribute the clock signal. The two conductor transmission line has a first conductor coupled to the clock signal and a second conductor coupled to the clock signal complement provides sub-circuits within the integrated circuit with a differential clock signal. Negative impedance transmission line terminations are then attached in parallel with the transmission line. The terminations boost the clock signal transition times and the clock signal complement transition times to provide high frequency circuit synchronization within the integrated circuit.
