Hi all ,
I am missing somewhere the fundamentals of opam.
As you can see in attached figure .
Iin= If
Now In= Vin /Rin
And If = Vout/Rf
Since Iin =If
Vin/Rin = Vout/Rf
On solving this we get
Vout = (Rf/Rin)Vout
So my doubt is why If is negative current I do not understand this. I tried to read the book but I did not understand can any let me understand the basic of this.
Thanks
