A new structure of primitive gates used in standard cell library

A novel digital logic circuit used in standard cell library is presented. In space application, the threshold voltage of NMOSFET will decrease, which influence the output characteristics of digital logic circuit seriously. With a new auxiliary circuit, the reliability and stability of digital logic gate circuit is improved. The structure configuration, circuit analysis and simulation result is compared with the traditional structure. The proposed circuit is simulated and verified in 0.18um CMOS process, which shows expected result.
