摘　　要：针对负偏置温度不稳定性引起的组合逻辑电路老化,提出了一款消除浮空点并自锁存的老化预测传感器。该传感器不仅可以预测组合逻辑电路老化,而且能够通过传感器内部的反馈来锁存检测结果,同时解决稳定性校验器在锁存期间的浮空点问题,其延时单元为可控型延时单元,可以控制其工作状态。使用HSPICE软件进行仿真,验证了老化预测传感器的可行性,可以适用于多种环境中且不会影响传感器性能。与同类型结构相比,该传感器的稳定性校验器能够对检测结果进行自锁存,使用的晶体管数量减少了约8%,平均功耗降低了约20%。Aiming at the aging of combinational logic circuits caused by negative bias temperature instability,a floating point eliminated and self-latching aging prediction sensor was proposed.The sensor can predict the aging of the combinational logic circuit,and can latch the detection result through the feedback inside the sensor.Meanwhile,it can solve the floating point problem of the stability checker during latching.Delay unit of the sensor is controllable delay unit,which can control its working state.HSPICE simulation results show that the sensor is feasible and can be used in many environments without affecting the performance of the sensor.Compared with the same type of structure,the stability checker of the sensor can latch up the predicted results,the number of transistors used in the sensor is reduced by about 8%,and average power consumption is reduced by about 20%.
