This material fits well with the desired coverage in some programs but not may not fit within others due to time constraints or local preferences. This supplement which is referenced in Chapters 2 and 6 assumes that the reader has studied the subsection CMOS Circuit Technology in Section 6-1 Chapter 6 4th Edition. This supplement contains sections on Complex Gates Three-state Buffer Implementation Transmission Gates and Transmission Gate-Based Flip-Flops. These sections are largely independent except that the Flip-Flop material depends on the Transmission Gates section. The material in this section is particularly appropriate for coverage by electrical engineering and computer engineering students not expected to study similar material in other courses. So far we have dealt largely with implementing logic circuits in terms of gates. In this supplement we continue the exploration of implementing gates and logic using CMOS technology that we began with CMOS Circuit Technology in Chapter 6. CMOS implementation is important because we sometimes design CMOS logic from Boolean equations directly to the transistor level skipping the logic gate level. Complex Gates Note that all of the circuits studied in Section 6-1 operate under DeMorgan s laws i. e. an output inversion property is characteristic of CMOS gates. In fact to devise a general design procedure for fully complementary CMOS circuits we assume that all functions are implemented as F F . This avoids working directly with p- 1 Pearson Education 2008.

Thus we design the n-channel network for F and take the dual to get the p-channel network for F For functions more complex than
