substrate terminal for passive devices - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

In CMOS designs is there any need to connect the substrate terminal of passive devices to ground?

It is probably best to make some sort of connection to ground. If the device is setting in a WELL (such as a PMOS) the "substrate" (not really a sub tie but an NWELL tie) is used to place the WELL to a high voltage otherwise the device will not work properly.
