CMOS has . . . . . . . . A. High noise margin B. High packing density C. High power dissipation D. High complexity

High noise margin
High packing density
High power dissipation
High complexity

The correct answer is: B. High packing density.

CMOS (Complementary Metal Oxide Semiconductor) is a type of semiconductor technology that uses both NMOS (N-channel Metal Oxide Semiconductor) and PMOS (P-channel Metal Oxide Semiconductor) transistors. CMOS is used in a wide variety of electronic devices, including microprocessors, memory chips, and integrated circuits.

One of the advantages of CMOS is its high packing density. This means that CMOS devices can be packed very closely together, which allows for the creation of very small and complex electronic devices.

The other options are incorrect for the following reasons:

  • A. High noise margin. CMOS does not have a high noise margin. This means that CMOS devices are more susceptible to noise than other types of semiconductor devices.
  • C. High power dissipation. CMOS does not have a high power dissipation. This means that CMOS devices are more energy-efficient than other types of semiconductor devices.
  • D. High complexity. CMOS is not a complex technology. This means that CMOS devices are relatively easy to design and manufacture.
