Abstract :
Noise may limit system performance, or it may push the system to malfunction. Hence a good system design has to take care of the noise problem. This paper addresses this issue and presents models to compute the noise immunity of dynamic CMOS circuits in submicron regime. Our models compute the maximum safe amplitude of a noise pulse in terms of the pulse duration as well as the circuit parameters. Also in these models the mobility degradation and velocity saturation have been taken in account. We have considered the cases where noise pulse is applied to one of the circuit inputs or the clock input. HSPICE simulations confirm the validity of these models
