我们提出了一种非均匀环形振荡器(RO),其性能受到一小组晶体管的强烈影响,用于表征晶体管的晶体管变化。晶体管的性能灵敏度的提高,通过插入一个“奇点”到一个均匀的RO。提出的RO已被嵌入在一个65 nm的RO阵列测试结构,它被验证,提出的RO是高度敏感的芯片内(WID)的局部变化和随机电报噪声(RTN)。从WID频率变化提取阈值电压(VthN和VthP)和沟道长度(L)的随机变化量。振荡频率的时间变化,由于RTN观察到在非均匀RO。
We propose an inhomogeneous ring oscillator (RO) whose performance is strongly influenced by a small set of transistors for characterizing transistor-by-transistor variability. Performance sensitivities of the transistors are enhanced by inserting a “singular point” into a homogeneous RO. Proposed ROs have been embedded in a 65nm RO-array test structure, and it is verified that the proposed ROs are highly sensitive to Within-Die (WID) local variability and Random Telegraph Noise (RTN). The amounts of random variation in threshold voltages(VthN and VthP) and channel length(L) are extracted from the WID frequency variation. Temporal variation of oscillation frequency due to RTN is observed in the inhomogeneous RO.
