CMOS circuits utilize complementary MOSFETs, i.e; NMOS and PMOS devices together in various patterns to create functional blocks like AND or OR gates. However the problem with these types of CMOS circuits is that they are inherently low power circuits. They cannot handle large currents. So when your block needs to have a large fan out (need to drive a large no of outputs, i.e; more current required) CMOS circuits fail. That is why we use BiCMOS. They are very similar to CMOS circuits except for the BJT(Bipolar Junction Transistor) output stage. BJTs are capable of carrying large currents, hence BiCMOS circuits are used in cases of large current requirements.

What are the Disadvantages of cmos over pmos 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 CMOS technology?
Complementary metal-oxide-semiconductor(CMOS) is a technology for constructing integrated circuits.
How can you implement c-bicmos using nand gate?
draw its cmos equivalent and give its output to pull up bjt.then draw nmos block of the logic and connect its drain to
What is submicron cmos technology?
The sub-micron CMOS technology has channel length less than 1 micrometer
What has the author Kerry Steven Lowe written?
Kerry Steven Lowe has written: 'Gate sizing and buffer insertion methods for optimizing delay and power in CMOS and BiCMOS logic networks'
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 difference between CCD camcorders and CMOS camcorders?
CCD camcorders and CMOS camcorders have huge differences, mostly the graphics and frames the camcorder may get. One may be HD while the other is only 240P
Which of the technology results in least power dissipation?
CMOS
How big are the transistors on the Pentium 1 processor?
The size ranged between 0.8 um to about .25um. Clock speeds range between 60 to 300 Mhz. The first 3 pentiums were in fact BiCmos.... integrating both Bi-polar and metal oxide semiconductor (MOS) transistors. Was not until the Pentium 4 arrived where they went complete CMOS. Reasons for this were mainly fabricating related. Commercially CMOS did take over but for high performance Bi-Polar is still used.
Why do you need a CMOS on motherboard?
You do not need CMOS circuits per se but that's the way many modern components are manufactured. Complementary metal-oxide-semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used inmicroprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for a wide variety of analog circuits such as image sensors, data converters, and highly integrated transceivers for many types of communication.
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.
What type of product is a cmos mux?
A CMOS Mux is a piece of technology that is used to create integrated circuits that are used in electronics. The full name of 'CMOS' is Complementary Metal Oxide Semiconductor.
