| Abstract: | Current mirror is a basic form in the analog integrated circuits, which consists of two or more parallel current branches. They are in proportion on certain ratio relationship each other. Research and discussion on CMOS circuit mirror＇s theory and technology is of important significance. This paper introduces CM＇s basic principle simply（based on NMOS CM）, analyses its application in difference amplifier and demonstrates its characteristics, and discusses a kind of high-swing CM structure. |
| Keywords: | current mirror differential amplifier active loads |
