What is the difference between NMOS, PMOS and CMOS transistors?
Can you tell me the difference between NMOS, PMOS and CMOS transistors?
NMOS, PMOS, and CMOS are different types of transistors used in digital electronics. 

[NMOS] An NMOS (n-type metal-oxide semiconductor) transistor is made using a p-type substrate, with the source and drain regions doped with n-type material. When a voltage is applied to the gate, it creates an electric field that allows electrons to flow from the source to the drain region. 

[PMOS] A PMOS (p-type metal-oxide semiconductor) transistor is made using an n-type substrate, with the source and drain regions doped with p-type material. When a voltage is applied to the gate, it creates an electric field that allows holes to flow from the source to the drain region. 

[CMOS] A CMOS (complementary metal-oxide semiconductor) transistor is a combination of NMOS and PMOS transistors. It uses both p-type and n-type substrates and allows for low power consumption and high noise resistance, which makes it ideal for use in digital circuits.
