Modélisation et analyse temporelle d’un bus d’interconnexion en technologie GaAs

The author presents the theoretical methods for modeling and transient analysis of coupled transmission lines. For an interconnecting bus used in GaAs technology with a 30 ps rise time activating signal and 3 mm length, he shows the great importance of coupling: signal distortion on the activated lines and parasiting on the unactivated ones. He studies the reduction of these phenomena with use of earth lines or addition of a second ground plane over the lines.
