NMOS
NMOS
Advantages
1. Less number of diffusions required. Hence cost per gate is the lowest.
2. Very low power dissipation(nW)
3. Variability in power supply (from 5-15 V) possible.
4. Very high noise margin. Suitable for use in industrial appliances.
5. Large fan out capability (20 gates )
6. MOS circuits are used as capacitors. They can also be used as resistors.
Dis-Advantages
1. MOS transistors are also capacitors. Hence speed of operation is lowest.
2. Large propagation delay of gate.
3. Higher power dissipation than CMOS gates.
