Could somebody explain to me how calculate the 3db frequency of this circuit? I would appreciate being shown where I went wrong in my calculations (picture).
What I don't want: somebody to just say something to the effect of fo=1/2pi*C*R, like what every single search result on the history of the internet comes up with in every forum where the question is asked..
I'm using the point where the magnitude of the transfer function drops to 1/sqrt(2), and solving for wo manually, not just by 'inspection'. I have a feeling I made a simple error in my equation, and am not totally off...(answer i got is on the same order of magnitude..) :/
Rs=20k, Ri=80k, Ci=5pF
Thanks you
