Title: how can I simulate guard rings? Post by dog1 on Mar 21st, 2014, 6:07am Hi guys, I am simulating an LNA at 60GHz and need some inductors there. And I need to incorporate the couplings between the inductors and other structures. However, I don't know if there is a way to incorporate the effect of the guardring in the simulation when dealing with those couplings. Right now, I mostly use momentum for the simulation of large metal structures like inductors, but the effect of the guarding ring in the substrate can not be taken into consideration there. And also in the process I uses a lower metal shielding is not recommended, thus the effect of the guarding ring is very important. Thanks! |
Title: Re: how can I simulate guard rings? Post by Andrew Beckett on Apr 7th, 2014, 2:35pm QRC can extract substrate connections, and can also extract inductance. There was a paper on using QRC to extract designed inductors (in addition to parasitic inductance) at CDN Live! EMEA a couple of years ago - http://www.cadence.com/pages/dh.aspx?vfile=/cdnlive/library/documents/2012/eu/CD04_HanssenM_NXPsemiconductors.pdf&topic=CDNLive!%20EU%202012%20Proceedings - you'll need a login to access this, but the site allows you to create one. Regards, Andrew. |
