Problems solved by technology

However, the existing one-bit full adder based on CPL logic with the same gate of FinFET has the following problem: the one-bit full adder generates sum signal S and carry signal C by inversion O , it needs to be equipped with a FinFET tube that forms an inverter function, which will inevitably increase the key jump node, resulting in an increase in circuit power consumption and delay, and the power consumption and power consumption delay product are large

The one-bit full adder is low in power consumption and power consumption time delay product.

Description

technical field [0001] The invention relates to a one-bit full adder, in particular to a one-bit full adder based on FinFET hybrid logic. Background technique [0002] As a basic unit of an electronic system, a full adder can not only complete addition, but also participate in operations such as subtraction, multiplication, and division, and is widely used in large-scale integrated circuit design. The full adder is an important unit of a digital signal processor, a microprocessor, and a single-chip microcomputer system with relatively high performance requirements. The performance of the full adder has a particularly important impact on the performance of the entire system. One-bit full adder is widely used in the carry critical path of multi-bit adder, and is one of the important factors affecting multi-bit adder. FinFET tube (Fin Field-Effect Transistor, Fin Field-Effect Transistor) is a complementary metal oxide semiconductor (CMOS) transistor, which has the advantages o...
