Pseudocmos nor

Here we see an example of a simple pseudoCmos nor gate. The pmosnet work consists of only one p Cmos transistor whose gate is connected to the ground , while the nmos network is the same as in static Cmos architecture.Doing so, the p cmos is always on.The pseudoCmos architecture has the great advatage of requiring much less surface to be fabricated than the other two architectures(static,dynamic).However, due to the fact that the pmos trans is always on, the pseudoCmos arch consumes more power than the statin and the dynamic archs do.Moreover,the output never reaches zero and we may have various issues because of this.
