|---|---|---|
A completely-digital, on-chip performance monitor is newly proposed in this paper. In addition to a traditional ring oscillator, the proposed monitor has a special buffer chain whose output duty ratio is emphasized by the difference between NMOS and PMOS performances. Thus the performances of NMOS and PMOS transistor can accurately be estimated independently. By using only standard cells, the monitor achieves a small occupied area and process portability. To demonstrate the accuracy of performance estimation and the usability of the monitor, we have fabricated the proposed monitor using 90 nm CMOS process. The estimated errors of the drain saturation current of NMOS and PMOS transistors are 2.0% and 3.4%, respectively. A D/A converter has been also fabricated to verify the usability of the proposed monitor. The output amplitude variation of the D/A converter is successfully reduced to 50.0% by the calibration using the proposed monitor. |
