Frequency divider circuit with anti-irradiation function

Abstract

The invention discloses a frequency divider circuit with anti-irradiation function, comprising more than three frequency divider units and a voting unit, wherein the output ends of each frequency divider unit are respectively connected to the input end of the voting unit, and the output end of the voting unit is in feedback connection to the input ends of each frequency divider unit. The frequencydivider circuit has the advantages such as simple structure, low cost, anti-irradiation function and low soft error rate.

Description

technical field [0001] The invention relates to the technical field of frequency dividers, in particular to a frequency divider circuit with an anti-radiation function. Background technique [0002] In order to meet the demand for integrated circuits with higher integration, more functions and lower power consumption, the feature size and operating voltage of integrated circuits have been continuously reduced, resulting in a sharp increase in the radiation sensitivity of circuits. The frequency divider is an important part of the integrated circuit. In the prior art, the frequency divider usually does not have the anti-radiation function. Once the radiation is affected, the output of the frequency divider will be affected by the single event effect and an error will occur. Seriously affect the performance of the circuit. Therefore, it is urgent to provide a frequency divider circuit with an anti-radiation function, so as to improve the anti-radiation performance of the freq...
