Measurements on a High Speed Arbiter

Lookup NU author(s): Professor David Kinniment



Measurements on a submicron CMOS arbiter implementation are presented. Using two uncorrelated asynchronous inputs to the arbiter effective time differences between requests of as low as 10-18 sec can be obtained. The metastability time of the arbiter is plotted against input request time difference and is shown to conform to the classical logarithmic relationship. In submicron CMOS, capacitances are sufficiently low to observe discreteness of charge effects, but thermal noise is more than two orders of magnitude larger than the quanta of voltage represented by the charge on an individual electron, and therefore masks these effects.
