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.
