What do the initials CMOS stand for?

The initials CMOS stand for Complementary Metal-Oxide Semiconductor. This technology is fundamental in the design of many integrated circuits, including microprocessors, microcontrollers, and digital logic circuits. CMOS technology is known for its high noise immunity and low static power consumption, which makes it particularly suitable for battery-operated devices.

In CMOS technology, two types of semiconductor switches are used – n-type and p-type – allowing for complementary digital logic. This complementary nature is what gives CMOS its name, as the two types of transistors complement each other during operation, thereby enhancing power efficiency and performance.

Understanding the correct terms and their implications is crucial in the field of electronics, particularly in contexts such as digital design and fabrication processes. The other choices represent variations that either do not exist or do not pertain to the accurate definition of CMOS.
