A Transistor-Based AND/XOR Gate Circuit

Abstract

The invention discloses a transistor-level AND / XOR gate circuit, which is characterized in that it includes a first transmission gate logic module, a second transmission gate logic module and a complementary CMOS logic module; the advantage is that in the complementary CMOS logic module, the first The PMOS transistor and the first NMOS transistor form the first inverter, the second PMOS transistor and the second NMOS transistor form the second inverter, the third PMOS transistor and the third NMOS transistor form the third inverter, and the eighth PMOS transistor and the eighth NMOS tube form the fourth inverter, the first transmission gate logic module and the second transmission gate logic module not only reduce the short-circuit power consumption, but also reduce the subthreshold power consumption of the fourth inverter, so that the circuit The overall power consumption is reduced; the four inverters enhance the overall drive capability of the circuit; the circuit structure of the invention is simple and relatively symmetrical, and is convenient for the layout of the layout.

Description

technical field [0001] The invention relates to a compound gate circuit, especially a transistor-level AND / exclusive OR gate circuit. Background technique [0002] With the continuous shrinking of integrated circuit process size and the rapid development of design technology, integrated circuits are developing towards larger scale and more complex trends, and power consumption has become one of the severe challenges facing the development of integrated circuits. At present, almost all circuit design methods use Boolean logic based on "AND", "OR", and "NO" operation sets, which can be called Traditional Boolean (TB) logic. It can be argued that some of the challenges facing IC design today are due to the inherent limitations of traditional Boolean logic. In fact, digital circuits can be implemented with traditional Boolean logic based on "AND or NOT", or Reed-Muller (RM) logic based on "AND / XOR (AND / XOR)". [0003] Delay, power consumption, and power consumption-delay produ...

AI Technical Summary

Problems solved by technology

In the early days, due to the technical level, the application of integrated circuit design based on RM logic was limited.

In recent years, the research on the AND / XOR gate circuit structure has broken through the traditional circuit structure formed by cascading AND gates and XOR gates, and proposed a new AND / XOR gate circuit structure based on transistor-level design, but There are still problems such as long delay and high power consumption
