AI Technical Summary

Problems solved by technology

The number of FINFET tubes used in the full adder is relatively large, resulting in large circuit area and power consumption; and the pull-down network stack composed of N-type FINFET tubes N1, N2, N3, N4, N5 and N6 has a high height, The pull-up path composed of P-type FINFET tubes P4, P5, P6, P7, P8, P9, P10, and P11 has a long path and a large delay, which is not conducive to fast evaluation

Abstract

The invention discloses a full adder based on a FinFET device. The full adder comprises a first N type FinFET tube, a second N type FinFET tube, a third N type FinFET tube, a fourth N type FinFET tube, a fifth N type FinFET tube, a sixth N type FinFET tube, a seventh N type FinFET tube, a first P type FinFET tube, a second P type FinFET tube, a third P type FinFET tube, a fourth P type FinFET tube, a fifth P type FinFET tube, a sixth P type FinFET tube, a seventh P type FinFET tube, an eighth P type FinFET tube, a ninth P type FinFET tube, a first inverter and a second inverter. The full adder has the advantages that the circuit area, the delay, the power consumption and the power delay product are smaller without affecting the circuit performance.

Description

technical field [0001] The invention relates to a full adder, in particular to a full adder based on a FinFET device. Background technique [0002] As the process size enters the nanometer level, power consumption has become a problem that IC designers have to pay attention to. The full adder is the basic unit of all arithmetic circuits and one of the most critical components of the digital system. The power consumption and operation speed of the full adder directly determine the overall performance of the entire circuit system. Zipper CMOS full adder, as a representative of dynamic full adder, is widely used in the pipeline structure and critical path of microprocessors due to its fast speed and small area at the 90nm technology node. It is the multiplication and accumulation unit in the processor essential component. However, with the rapid development of CMOS integrated circuit technology, the device size is continuously reduced, and the clock frequency of the micropro...
