Description

technical field [0001] The invention relates to a ternary multiplier, in particular to a multi-bit ternary low power consumption domino multiplier. Background technique [0002] The current digital circuit system is mainly implemented by binary logic, and the logic values ​​that can be transmitted by a single signal line are only 0 and 1, and the space and time utilization of the circuit is low. The use of multi-valued logic can greatly reduce the number of circuit input variables and increase the amount of information carried by each connection, thereby reducing the area of ​​the chip and enhancing the data processing capability. Due to its advantages in circuit area and speed, domino circuits are widely used in various high-performance circuits. Therefore, combining multi-valued logic with domino circuits can further reduce the circuit area and increase the information density of the circuit. [0003] Multipliers are one of the key components of modern digital systems and...
