Hi,
We know that the gain of an inverting amplifier A = -Rf/Rin. However, lets say I want a gain of 10 V/V. Which resistor value would you choose and why?
I know that you could have infinite number of combinations for these resistors but why would some one use specific value. i.e Rf = 100Mohm, Rin = 10Mohm gives a gain of 10V/V but also Rf = 10 ohm and Rin = 1 ohm gives the gain of 10V/V. What difference would it make to the design?

Hari
