What are the advantages of CMOS process?

The main advantage of CMOS logic family is their extremely low power consumption. This is because there is no direct conducting path from Vdd to ground in either of input conditions. So there is practically zero power dissipation in STATIC conditioms.

What is N well process?

The N-well / P-well technology, where n-type diffusion is done over a p-type substrate or p-type diffusion is done over n-type substrate respectively. The Twin well technology, where NMOS and PMOS transistor are developed over the wafer by simultaneous diffusion over an epitaxial growth base, rather than a substrate.

What is CMOS and NMOS?

CMOS stands for Complementary Metal-Oxide-Semiconductor whereas NMOS is a negative channel metal oxide semiconductor. CMOS and NMOS are two logic families, where CMOS uses both MOS transistors and PMOS for design and NMOS use only field-effect transistors for design.

What is CMOS inverter in VLSI?

A CMOS inverter is a field-effect transistor that is composed of a metal gate that lies on top of an insulating layer of oxygen, which lies on top of a semiconductor. CMOS inverters are found in most electronic devices and are responsible for producing data within small circuits.

What is the full form of NMOS?

An N-channel metal-oxide semiconductor (NMOS) is a microelectronic circuit used for logic and memory chips and in complementary metal-oxide semiconductor (CMOS) design. NMOS transistors are faster than the P-channel metal-oxide semiconductor (PMOS) counterpart, and more of them can be put on a single chip.

How many terminals are there in NMOS?

A Metal Oxide Semiconductor Field Effect Transistor (MOSFET) has 4 terminals Gate, Drain, Source and Substrate (Body) terminal. But in many practical circuits MOSFET is used by connecting three terminals Gate, Drain and Source while connecting Substrate (Body) terminal to source.

What is the difference between MOSFET and CMOS?

Basically mosfet acts like an electronic switch, as well as voltage regulator. CMOS means complementary metal oxide semiconductor feild effect transistor. CMOS is the combination of both PMOS AND NMOS. Basically CMOS acts as a inverter.

What is noise margin in CMOS?

Noise margin is the amount of noise that a CMOS circuit could withstand without compromising the operation of circuit. It is basically the difference between signal value and the noise value.
