Hello,
I have two questions:
When we want to design an op-amp circuit to be a non-inverting amplifier ,according to what do we put the values of the input and output resistances ?
are there any limitations ?
if I want to to put a gain of 10 times the input signal , can I choose any values that lead to 10 gain ? for example I want to amplify a 10mv ,so I put the values 100k and 900k for the input and output resistances respectively.
or I can choose another values ,1k and 9k ,which also gives a gain of 10 !!?
Also, I want to ask about he Vcc and what is the impact of it on the amplified signal ?
