    摘要: A simultaneous switching noise (SSN) test circuit and method are provided for measuring effects of SSN. Prior to testing for SSN, a signal is applied to the victim signal input pad and the rise and fall time delays associated with the victim signal are measured at the victim signal output pad. Then, one or more aggressor signals are simultaneously applied to respective input pads of one or more respective aggressor signal paths. The rise and fall time delays of the victim signal transmitted by the output pad are then measured and compared to the previously measured rise and fall time delays to determine effects of SSN on the victim signal caused by the aggressor signals.

    摘要: An active termination technique for reducing the propagation delay of a signal across a transmission line is presented. In accordance with a preferred embodiment of the invention, repeaters along a transmission line are paired with active termination circuits in very close proximity to the repeater in order to prevent signal reflections caused by the repeaters. The repeaters and associated active termination circuits are implemented with at least one PFET and at least one NFET, each having the same transistor gate lengths. The PFETs and the NFETs in the repeater and associated termination are ratioed to vary similarly over process/voltage/temperature variation.
