How to implement this transfer function using SC filters?

[rampat]

i have transfer function for my filter as following,

H(s) = -47.826E03*s/ [(5E5+s)*(s+304.34)]

Can anyone tell me how implement this using SC filters?

SC implemantaion

u can use biquad structure to get this BPF TF.
See ch9.6 of "CMOS analog circuit design; Phillip E. Allen..."

Re: SC implemantaion

First, you need to transfer the filter from s-domain to z-domain.
You can use bilinear transformation.

Then you get the coefficicent in z-domain.

After that, you need to choose high-Q or low-Q SC architecture.

Usually, low-Q SC has small area.
