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

Im designing a CMOS low noise amplifier
and would like to generate the input return loss
circles of the amplifier for different values. For
example -10 dB, -15 dB and -20 dB. I know that if
the amplifier is going to be matched to S11* at
the working frequency teoretically the input return
loss would be infinity, and is represented as a
point in the smith chart. So what im looking for
is a manner to generate the various cicles for finite
By the way...
Im using ADS to design
