Filter Transfer Function
Hi ALL,
I have some problem to relate the transfer function of my filter with the working frequency of my filter design.
The transfer function of my filter (active) block was like below
D
H(s) =---------------------
AS³+BS²+CS+1
where A,B,C,D are in term of gm (transconductance of the OTA in th ecircuit),R and C.
The filter is design as a 3 pole Butterworth LPF. And passband frequency is 500KHz.
So, my question is how can I related the frequency with the transfer function that I have with the passband frequency and determine the value of R and C?
Thanks
