What is the difference between cmos and nmos?
CMOS and NMOS are two logic families. As the name itself indicates, CMOS is complementary Metal Oxide Semiconductor technology. It uses both PMOS and NMOS transistors for design. Whereas, NMOS logic family uses only NMOS FETs for design.
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.
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).
What is a NMOS PLA?
NMOS PLA is a Programmable Logic Array which is designed by employing NMOS technology i.e. by employing nmos transistors to realize the required gates of PLA. PLA is a combination AND gates and OR gates to produced sum of products terms needed for realizing the required combinational logic. It consists of an array of AND gates followed by OR plane. the connections to the AND and OR inputs can be programmed based on our needs.
Is cmos a combination of both nmos and pmos?
yes
What are the advantages of CMOS inverter over nMOS inverter?
Cmos inverter has very less power consumption when it is idle where as nmos inverter still consume power when idle.
What happens if you interchange pmos and nmos in a cmos inverter?
it becomes a buffer
What is the fullform nmos switches in 8086 microprocessor?
n-channel mosfet
Why p substrate is used in nmos?

What are the advantages of PMOS and NMOS?
PMOS is more immune to noise and has better controllability
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 are the Advantages of cmos over pmos and nmos?
* reduce the complexity of the circuit* low static power consumption* high noise immunity* high density of logic function on a chipThe most important advantage of CMOS is the very low static power consumption in compare with NMOS technology. On the other hand, CMOS technology is more complex to fabricate then NMOS technology, so it is more expensive. However, almost every todays digital circuits are CMOS. You want to use NMOS only when you want to fabricate fast and low-cost a simple circuit. The most important advantage of CMOS is the very low static power consumption in compare with NMOS technology.
