Advantages of CMOS Technology in Very Large Scale Integrated Circuits

Nowadays, complementary-metal-oxide-semiconductor (CMOS) is widely used in large scale integrated circuits. In this paper, two typical cases of Very Large Scale Integration (VLSI) are selected. CMOS technology is compared with other two commonly used technologies (Transistor-Transistor logic (TTL) and Emitter-coupled logic (ECL)), and the advantages of CMOS technology are analyzed. In the gate array, because of the advantages of temperature stability, stronger anti-noise ability and lower power consumption, CMOS technology is widely used. In the 5G communication, the cost of CMOS technology is much lower than it of ECL. The speed disadvantage of CMOS is also compensated for by certain technologies. For these reasons, CMOS technology is widely used in VLSI. This paper also prospects the improvement space of other technologies, and how to improve other technologies can make it more widely used in VLSI is discussed. Taking advantage of the gain advantage could help TTL technology become more mainstream in some types of integrated circuits, and solving the cost problem could lead to significant improvements in ECL technology.
