摘要
The transmission function theory is proposed, the quaternary and logic variables are distinguished, and three kinds of new operations (i.e. the threshold comparison operation, transmission operation and union operation) are introduced. Since these operations describe the action principle of metal-oxide semiconductor (MOS) transistors, the transmission functions expressed by using them and logic operations can direct the realization of quaternary complementary metal-oxide semiconductor (CMOS) circuits. In this paper the design of CMOS circuits for some basic transmission functions is proposed. The computer simulation has confirmed that these circuits have correct logic and desirable DC transfer characteristics. Furthermore, the synthesis technique for a quaternary CMOS transmission network is also proposed here.
