A p-type substrate is used in NMOS transistors because it provides a foundation for creating the n-channel within the substrate. By creating a p-n junction with the source and drain regions, a conductive channel can be formed in the p-type substrate when a voltage is applied to the gate, allowing current flow between the source and drain.

What is benzoyl DL-arginine p-nitroaniline hydrochloride?
Benzoyl DL-arginine p-nitroaniline hydrochloride is a synthetic reagent commonly used in biochemistry and molecular biology research. It is often employed as a substrate to measure the activity of proteolytic enzymes, particularly trypsin-like enzymes. The hydrochloride salt form helps with solubility and stability in aqueous solutions.
In an experiment of Pepsin and BAPNA is pepsin the substrate?
No, pepsin is not the substrate in the experiment with BAPNA. BAPNA is the synthetic substrate used in this experiment to test the activity of the enzyme pepsin by measuring the rate of substrate cleavage. Pepsin acts on BAPNA as the enzyme, not the substrate.
What is CRS substrate?
CRS substrate, or Cold Rolled Steel substrate, is a type of material used in the production of various steel products. It is formed by rolling steel at room temperature to give it a smooth finish and desired dimensions. CRS substrate is commonly used in industries such as automotive, construction, and appliances.
Do an enzyme And its substrate fit together like a lock and key?
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
What is the substrate name for papain?
The substrate name for papain is typically referred to as "substrate Z" in enzymatic studies.
What are the differences between nmos and pmos transistors?
NMOS is built with n-type source and drain and a p-type substrate, while PMOS is built with p-type source and drain and a n-type substrate. In a NMOS, carriers are electrons, while in a PMOS, carriers are holes. When a high voltage is applied to the gate, NMOS will conduct, while PMOS will not. Furthermore, when a low voltage is applied in the gate, NMOS will not conduct and PMOS will conduct. NMOS are considered to be faster than PMOS, since the carriers in NMOS, which are electrons, travel twice as fast as holes, which are the carriers in PMOS. But PMOS devices are more immune to noise than NMOS devices. Furthermore, NMOS ICs would be smaller than PMOS ICs (that give the same functionality), since the NMOS can provide one-half of the impedance provided by a PMOS (which has the same geometry and operating conditions).
Why is the substrate in nmos connected to ground and in pmos to vdd?
we try to reverse bias not the channel and substrate but we try to maintain the source,drain junctions reversed biased with respect to the substrate so that we dont loose our current in the substrate.
Why is always p-substrate is used in fabrication of FET?

What is NMOS in electronics?
when n- channel mosfets are used to construct a circuit these are called nmos(N- channel mosfet).
What are advantages of transmission gate logic over Cmos logic?
cmos logic circuit uses particularly pmos or nmos viz. passes strong 1 and strong zero respectively and also degraded zero's and one's in their respective cases of p and nmos so to remove deggraded output the nmos and pmos are combined together for strong output level
What is the use of pseudo nMOS gates in digital design?
These circuits use nMOS for implementation of a whole gate + one pMOS which is connected between positive supply and nMOS.
Why p-substrate is used in monolithic IC not p-substrate?
entire circuit is built into a single piece of semiconductor (chip); physical properties of semiconductor to large degree determine performance of the circuit; the most common integrated circuits such as microprocessors, memories, etc., are all monolithic.
Define pinch off voltage and the gate source cut off voltage?
If negative voltage is applied to the gate of a NMOS, it repels electrons from the channel region towards the bulk of the p-substrate and attaract holes from p-substrate towards the channel. The recombination between holes and electrons causes a deplation of majority carriers in the channel. Enough nagative gate voltage can cause the channel depleted of majority carriers and cuts off the current between the source and the drain. The least negative gate voltage causing this is called gate-source cut off voltage.
How mosfet works inspite of insulator under the gate how the gate attracts or rpels the charge carriers from substrate to form a channel?
For the Proper operation of NMOS Transistor Substrate and Source are connected to the Lower potential, If we are applying a positive Gate voltage with respected to Source Similarly The gate voltage is positive to Substrate Hence due to the body voltage, electrons are accumulated under the oxide layer and forming a channel for conduction.
The are used to conect with the substrate?
"The are used to conect with a substrate" is not a question, and connect is spelled incorrectly.
What are the different parasitic capacitances of NMOS transistors?
Parasitic capacitances form across every depletion region there's also a capacitance between the conductive leads to the terminals. For simplicity they are usually just lumped to each of the terminals of the transistor. Gate, Drain, Source and Substrate. If substrate is shorted to source creating typical 3 terminal representation then that half of those parasitic capacitances combine and Css (source-substrate) = 0. Cgd Cgs Cds (primarily from drain to substrate, not drain to source)
What type of doping have the drain and the source of a PMOS transistor?
PMOS - (drain + source) = p-type doping NMOS - (drain + source) = n-type doping :)
