Hello I am developing a low noise preamp and would like to change the roll off of my design to sharply decrease the gain for very low frequencies "1-5Hz". The results of my current design are as follows.
I would need something that looked more like this..
I understand the simple equations of changing the corner frequency and gain but I am unsure how to change the roll off. I recall I may have covered some of this in control systems but that was quite some time ago.
Ideally id like to replicate the results in the above bode plot and have good response (40db) for higher frequencies.
Any help is greatly appreciated!
