Practical and Theoretical Limits of CMOS Technology

Summary

This chapter discusses consumption problems, author just reminds the reader of these different problems and the solutions proposed to combat them. Complementary metal‐oxide‐semiconductor (CMOS) technology has made considerable progress in the realms of reducing transistor size since the 1960s. The amount of new specific circuits (ASIC) is diminishing every year because it is rarely cost‐effective to manufacture them in advanced CMOS technology. The last section attempts to set out the clearest possible aspects to identify the potential theoretical limits, which remain to be the subject of conflicting debates. The following calculation is very important, because it shows that CMOS technology is limited when it comes to energy properties. Contrary to the widespread idea, it is possible to make logic gates operate using a supply voltage that is weaker than the transistor thresholds in CMOS technology.
