The Application of Ccd's in Multiple-valued Logic
نویسنده
چکیده
The advantages and disadvantages of using multiple-valued logic in integrated circuits are discussed. The benefits of applying CCD's in the implementation of multiple-valued circuits are explained. The combination of a few basic multiple-valued logic (MVL) functions makes it possible to implement any MVL function. Three basic functions in four-valued, logic ho.ve been designed^ fabricated and tested.. These are the minimum^ maximum and complement functions. The latter has also the feature that it is able to regenerate the logical value. It is explained why four-valued logic is preferred at this moment. The CCD design principles however can also be applied for multiple-valued logic with other radices. The design considerations and operation principles of the devices are presented.3 and the performance data given.

A Novel Design of Quaternary Inverter Gate Based on GNRFET
This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...
متن کاملAlternating Regular Tree Grammars in the Framework of Lattice-Valued Logic
In this paper, two different ways of introducing alternation for lattice-valued (referred to as {L}valued) regular tree grammars and {L}valued top-down tree automata are compared. One is the way which defines the alternating regular tree grammar, i.e., alternation is governed by the non-terminals of the grammar and the other is the way which combines state with alternation. The first way is ta...
