摘要
负偏置温度不稳定性引起的晶体管老化已经成为影响集成电路可靠性的重要因素。高扇入多米诺或门是高性能集成电路中常用的动态电路,而负偏置温度不稳定性降低了多米诺或门的噪声容限并增大了其传输时延。本文提出了保持器和反相器均带有补偿晶体管的多米诺或门结构,通过开启补偿电路,使电路在老化以后仍然能够保持其抗干扰能力和传输延时,有效的延长了多米诺电路的使用寿命。
NBTI-induced transistor aging has become a prominent factor affetcing the reliability of circuits. Domino logic circuits are extensively app.lied in high-performance integrated circuits, but noise margin is decreased and transmission delay is＇increased due to NBTI-induced circuit aging. A domino logic circuit with compensating keeper and inverter is proposed. The noise margin and the speed are maintained by opening the compensating circuit after domino logic circuit aged, so the lifetime is prolonged.
