Note: Wide-range and high-resolution on-chip delay measurement circuit with low supply-voltage sensitivity for SoC applications

This paper presents an on-chip delaymeasurement (OCDM) circuit with a wide delay-measurement range, a high delay-measurement resolution and low supply-voltage sensitivity for efficient detection, and diagnosis in the high-performance system-on-chip (SoC). The proposed cascade-stagemeasurement structure can simultaneously achieve a delay-measurement range of several nanoseconds and a quantization resolution of several picoseconds. The proposed delay-measurement circuit has a high immunity to supply voltage variations without any additionalcalibration or self-biasing circuit. The delay-measurement range is 5.25 ns with 6 ps resolution; and the average delay resolution variation is 0.41% with ±10% supply voltage variations.
