hi
If the filter order > 3, there may have many R and C, how do I know to trim which element?
Any paper or book talk about the active filter's tuning/trimmig?
Thanks a lot.
Hi,
Can anyone tell me that an active filter needs a tuning circuit or not?
As I know, a gm-c filter needs tuning circuit, and I don't know if active filter needs?
Thanks.

Hi,
I need to know the group delay of a analog filter.
The "grpdelay" seems for figital filter.
If I use this function, how to translate the samples to time of Y axis?

excess phase
This paper provide a simple method to move the zero from right-half plane left-half plane.
I study this paper, and I am trapped on the fig.7 at page 446.
Can anyone tell me why the time constant is
(C1+C2+C1C2/Ci)/gm

hi,
I am working on a 3 order mult-bits delta simga and I am a new hand.
My question are
1. How to implement the circiut in digital system. Since all numbers in matlab are floating point. But in real circuit, I don't know how many bits adder should be used?
2. Should I change my simulation model...
