Based on the theory of NMOS design rules developed by Mead and Conway and CMOS features, concept of mixed design rules and its applications in Si-gate LOCOS CMOS technology are proposed. The typical geometrical and electrical parameters of the mixed design rules re given in this paper. The typical characteristics of CMOS ring oscillators, D-type flip/flops and operational amplifiers designed according to the mentioned rules are also described. Finally, standard colours and graphic representations for CMOS l...
