摘要

本文介绍了用片上噪声监测电路(OCM)测量5级逆变器链的功率噪声(Vdd噪声)波形。实现了0.4 mV电压和12.5 ps时序的精细分辨率。在I/O单元中信号缓冲器产生的不希望的电压变化通过三种方法仔细消除;(i)隔离功率域，(ii)减去背景噪声波形，以及(iii)对迭代捕获的波形进行平均。

Power-noise measurements of small-scale inverter chains

This paper presents the measurements of power noise (Vdd noise) waveforms of a 5-stage inverter chain, using on-chip noise monitor circuits (OCM). The fine resolution of 0.4 mV in voltage and 12.5 ps in timing are realized. The undesired voltage variation by signal buffers in I/O cells is carefully eliminated by three means; (i) isolation of power domains, (ii) subtraction of background noise waveforms, and (iii) averaging iteratively captured waveforms.
