Abstract

The invention discloses a pulse trigger based on a FinFET device. The pulse trigger comprises a first FinFET, a second FinFET, a third FinFET, a fourth FinFET, a fifth FinFET, a sixth FinFET, a seventh FinFET, a first inverter, a second inverter, a third inverter, a fourth inverter and a fifth inverter. The first FinFET, the second FinFET and the third FinFET are P type FinFETs; the fourth FinFET, the fifth FinFET, the sixth FinFET and the seventh FinFET are N type FinFETs; the number of fins of the first FinFET and the number of fins of the second FinFET are both 1; the number of fins of the third FinFET is 3; and the number of fins of the fourth FinFET, the number of fins of the fifth FinFET, the number of fins of the sixth FinFET and the number of fins of the seventh FinFET are 4. The pulse trigger has the advantages of being small in circuit area, time delay, power consumption and power consumption delay product.

Description

technical field [0001] The invention relates to a pulse trigger, in particular to a pulse trigger based on a FinFET device. Background technique [0002] In a digital circuit system, a sequential logic circuit is composed of a storage circuit and a combinational logic, the storage circuit maintains the state of the system, and the flip-flop is used as a storage circuit. Flip-flops play an important role in digital circuitry. Pulse trigger is a kind of trigger commonly used in digital circuit system. FinFET tube (Fin Field-Effect Transistor, Fin Field-Effect Transistor) is a complementary metal oxide semiconductor (CMOS) transistor, which has the advantages of high speed, low power consumption and small area. At present, FinFET tubes have been used in the design field of pulse triggers. [0003] The circuit structure diagram of an existing pulse trigger (same-gate pulse trigger) based on FinFET devices is as follows: figure 1 shown. The pulse trigger is composed of 4 P-t...
