The integrated circuit (IC) was little known before the 1960s. However, today in 2020, it is said that the integrated circuit is the product of civilization with the fastest progress in human science and technology in this century. Before the invention of the integrated circuit,human beings lived in an era of information scarcity. After the invention of the integrated circuit, people lived in an age of information explosion. Moore's Law [1]points out that the line width of the circuit within the IC is rapidly narrowing, and the difference in thickness is only 1/10 of the line width. This design specification makes the line width of the IC circuit smaller, and it is difficult to distinguish between the current signal and the current noise accurately.
