In an Inverting op amp, Which is the feedback parameter B?
According to this source https://ocw.mit.edu/courses/electri...ent-spring-2006/lecture-notes/22_op_amps1.pdf (p. 10), is Ri/Rf (Which I think is the right answer). But according to other sources, it seems to be Ri/(Ri+Rf), like in the Non-inverting topology.
Which is the right answer?
