CMOS is a read-write RAM chip on the computer motherboard.
Complementary metal oxide semiconductor (CMOS) is a design process of integrated circuits, which can make basic devices of NMOS and PMOS on silicon wafer templates. Because NMOS and PMOS are complementary in physical characteristics, they are called CMOS.
In general technology, CMOS can be used to make digital logic circuit systems such as static random access memory, microcontroller and microprocessor of computer appliances. In addition.
After some different processing, it can achieve special technical characteristics and can be used in optical instruments. For example, complementary metal oxide semiconductor image sensor devices have become very common in some advanced digital cameras, but CMOS is now mainly synonymous with photosensitive devices.
Advantages of CMOS technology
One of the biggest advantages of CMOS technology is low power consumption. Transistors in CMOS circuits are complementary pairs of N-type and P-type MOS transistors, which can reduce power consumption. In CMOS circuit, current will flow only when the input signal changes, and in static state, the circuit consumes almost no power.
So CMOS skills are widely used in smart phones, tablets and other devices that need to run for a long time and use batteries for a long time. CMOS circuit can also realize the generation and distribution of high-speed clock signals, which makes the working frequency of the circuit reach a very high level. This high-speed design can be applied to fields that need high-speed data processing and transmission.
