CMOS集成电路在迅速发展过程中也出现了一些问题,其中最严重的问题首先是锁定效应.它是CMOS电路的主要失效模式之一,也是提高CMOS集成度的一大障碍.CMOS的优越特性之一是对工作环境要求不高,就工作温度而言,可宽达-55～+125℃,但由下面的分析和实测结果可知,温度的变化将引起锁定灵敏度显著变化,在应用和分析设计中应给予注意. CMOS integrated circuit is also in the rapid development of some problems have emerged, the most serious problem is the first lock-in effect.It is one of the main failure modes of CMOS circuits, but also to improve CMOS integration is a major obstacle .CMOS superior features of First, the working environment is not demanding, as far as the operating temperature, wide as -55 ~ +125 ℃, but the following analysis and measured results show that the temperature changes will cause a significant change in lock sensitivity in the application and analysis of design Should pay attention.
