MOS gate[1]: The MOS tube as a switching element constitute the gate. MOS gate, especially a CMOS gate with simple manufacturing process, high integration, anti-interference ability, low power consumption, cheap, etc., has been very rapid development. The so-called CMOS (Complementary MOS), is in IC Design, while using two MOS devices: NMOS and PMOS, and the emergence of a circuit is usually paired structure. CMOS circuits and technology has become todays integrated circuits, especially large-scale circuits, VLSI mainstream technology. Inverter is a basic digital circuit modules. The two serial output of the inverter as a register input to constitute a latch. Latch, data selectors, decoders and state machines and other precision parts are required to use a few characters in the basic inverter. Therefore, the schematic for the CMOS inverter layout design and simulation is necessary to learn their own Tanner EDA software. Further understanding of the transient characteristics of CMOS inverter DC characteristics and layout drawing. Key words CMOS; inverter; TannerEDA; design; simulation; territ
