GMC filter

Hi every one ,

Can any one send me a program that I can design a GMC filter .


I used a program called "filter solutons" but it hasn't the GMC type.

I need it urgent please,

my e-mail is :

 

Dear Medo,

I'm usually using this group in the evening after work. But since your
request is 'urgent', I'm scarifying few minutes of my lunch time.
Are you looking for a ready made program/design for your application ?
I'm afraid it's not the right place to ask for this kind of things,
especially for urgent things:-(
BTW, since you are in a big hurry, why don't you give us more details
about your transconductance filter. Information like the Bandwidth,
the tuning frequency range and other stuff could be very helpful.
You're may be looking for something generic.

Anyway, you can do this under the Cadence DFII framework of course but
since you're looking for a 'programming' approach, the following link
lists plenty of tools:

I used to use Matlab myself which one of the industry standards and
sign-off tools nowadays (This comment is personal, not related to my
company's business and no advertisement intended). You can give a look
at Scilab (free) otherwise: http://www.scilab.org/.

Now if you need more about designing GMCs, just google it, there are
many papers available on the IEEE and other links, these are couple of
them:

Hope this help you !

Lunch time is over, I need to back to my work, my employer will fire
me otherwise ;-)
