Abstract :
This paper discusses the phenomenon of the interference, induced by the switching behavior of a device to other devices and how to reduce it in integrated circuits. We built up a simple model to study the characteristics of noise coupling through a common substrate. Also, we study many types of guard-ring and their efficiencies of noise-rejection. One NMOS is used as a switching device (noise-source), and another NMOS, biased in the linear region, to be the noise sensing device. The experimental results are consistent with the results from the HSPICE simulation using this model. The chip used for experimental verification is produced by TSMC (SPTM06 technology)
