WebMar 2, 2013 · Noise margin is the amount of noise that a CMOS circuit could withstand without compromising the operation of circuit. 2. 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'. 3. It is basically the difference between signal value and the noise value 3 ... WebThe noise margin changes depending on the signal source. Let's say an input stage needs a minimum of 3.0 V to guarantee a (whatever) output. If the signal source makes a nominal 4.0 V output, that is a 1.0 V margin. If it makes a 5.0 V nominal output, that is a 2.0 V margin.
