What are the advantages of 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.

What is CMOS latch up?
Latch-up in short is defined as the creation of a low impedance path between the power supply rails by the triggering of parasitic, four-layer bipolar structures (SCR’s) inherent in CMOS technology.
Does low load in transformer lead to low power factor?
Power factor is determined by the nature (resistive, inductive, capacitive) of a load, not whether it is a low load or a high load.
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
Why low power VLSI technology is preferredover VLSI technology?
Low power VLSI is preferred over VLSI.It is because of the following reasonsIt consumes less power i. e. the power consumption is lowThe power dissipation is also lowmost of the modern devices need to operate at low powerComplex systems can be designed with reliability as the power consumption is low.We use modern electronic devices like mobiles ans robotics. These are generally compact and movable. Hence, they operate with a battery rather than power connection. Hence, we need low power operation.
What is static power?
Static Power could be equated with leakage for CMOS. Different values could be given for energies for various conditions of a cell, e.g. static power for output=high and for output=low
Extremely low power dissipation and low cost per gate can be achieved in?
cmos ics
Why is CMOS so important in modern electronics devices such as IPod's?
low power
What is a typical advantage of CMOS over TTL?
TTL stands for Transistor-Transistor-Logic. N-MOS is a type of a metal oxide semiconductor technology. TTL is faster, but generally uses more power. MOS based devices are slower, they and they use less power. Speed is an issue when dealing with high speed data processing.
What is the differences among TTL and CMOS logic families?
{| ! CMOS ! TTL | CMOS has good packing density. TTL takes up more space CMOS has better noise immmunity. TTL has a smaller noise immunity range CMOS has a large fan out. TTL can power less inputs CMOS consume less power. TTL use more power CMOS are highly static sensitive. TTL IC's tend to be less susceptible to static electricity CMOS uses FETS (Field-Effect Transistors) TTL uses BJTs (Bipolar junction Transistors CMOS can run with a range of supply voltages. TTL IC's run with a 5V supply. CMOS uses Vdd and Vss for it's power connections TTL uses BJTs (Bipolar junction Transistors CMOS takes a lot less power and is therefore suitable for battery applications, but generally speaking can't run as fast. TTL devices can drive more power into a load. CMOS chips can be damaged by static electricity: even a static jolt that you or I can't feel might destroy a CMOS chip! |}
What are the differences between mos technology and bipolar technology?
cmos advancements: a.)low static force dispersal b.)high info impedance c.)versatile limit voltage bipolar innovation: a.)high power dispersal b.)low info impedance c.)low voltage swing rationale
What is the meaning of hc in 74hc245?
In the context of "74HC245", "HC" stands for High-Speed CMOS (Complementary Metal-Oxide-Semiconductor). This indicates that the 74HC245 is a type of CMOS integrated circuit that operates at a high speed.
Why CMOS is important?
In many devices, the technology is enabled in some of the memory to store the date, time, and other important information. This is due to the very low power consumption of CMOS.

What is the difference between TTL and CMOS interms of fan infan outlogic levelspropagation delay?
The power dissipation of CMOS devices is around 100 times lower than the value of power dissipation for TTL. This makes CMOS more suitable for devices to run on battery power and devices allows like mobile phones to have a longer batter life. CMOS devices only use power when switching from one state to the other state (high to low, or low to high) so on they need power for less of the time than TTL devices which use current and dissipate power all the time that they have a power supply.
What is lpc in lpc2138?
Low Powered CMOS
What is CMOS latch up?
Latch-up in short is defined as the creation of a low impedance path between the power supply rails by the triggering of parasitic, four-layer bipolar structures (SCR’s) inherent in CMOS technology.
