In general, the low noise margin is considerably worse than the high noise margin for Pseudo-nMOS.Noise margin is the amount of noise that a CMOS circuit could withstand without compromising the operation of circuit. Noise margin does makes sure that any signal which is logic ‘1’ with finite noise added to it, is still recognized as logic ‘1’ and not logic ‘0’. It is basically the difference between signal value and the noise value.
