What Is a Complementary Metal Oxide Semiconductor?
A complementary metal oxide semiconductor, or CMOS, is the basic logic controller that is used in an integrated circuit. Complementary metal oxide semiconductor design technology is traditionally found in microprocessors used in computers, computer memory, and mobile printed surface board technologies, such as mobile phones and handheld computing devices. The key selling point of a CMOS device is its very low rate of power consumption, as compared to the other logic technology available, the transistor-transistor logic (TTL). The CMOS utilizes two different metal combinations to establish the logic gateway that enters into the complementary metal oxide semiconductor. As such, the resistance between these two metals is very high. Consequently, by following Ohm’s law that voltage equals current times resistance, the higher the resistance, the less current that is required to maintain a given voltage.
