Problem 3 The circuit below is a non-inverting amplifier with an OP-AMP and two resistors. (a) Find the non-inverting amplifier voltage gain (G) when the OP-AMP gain (A) is 100V/V, the OP-AMP input resistance
(r_(i))is
\infty , and the OP-AMP output resistance
(r_(0))is 0 . Hint: No approximation needed. (b) Find the non-inverting amplifier input resistance
(R_(i))when the OP-AMP gain
(A)is
1000(V)/(V), the OP-AMP input resistance
(r_(i))is
20k\Omega and the OP-AMP output resistance
(r_(o))is
80k\Omega Hint: Assume
Ais large enough. (c) Find the non-inverting amplifier output resistance
(R_(o))when the OP-AMP gain (A) is
1000(V)/(V), the OP-AMP input resistance
(r_(i))is
20k\Omega and the OP-AMP output resistance
(r_(0))is
80k\Omega . Hint: Assume
Ais large enough.
