Figure (Q1) shows an ideal voltage amplifier with a gain of +2 V/V implemented with an Op Amp connected in the noninverting configuration and a resistance R connected between the output and the input. a) Using Miller's theorem, show that the input resistance is Rm = -R b) Using Norton's theorem to replace Vig, Rig, and Rin with a signal current source and an equivalent parallel resistance. Show that by selecting Rig = R, the equivalent parallel resistance becomes infinite and the current I, into the load impedance Z, becomes Vig /R +2 R Figure (Q1)

Question
Figure (Q1) shows an ideal voltage amplifier with a gain of +2 V/V implemented with an Op Amp connected in the noninverting configuration and a resistance R connected between the output and the input. a) Using Miller's theorem, show that the input resistance is Rn = -R b) Using Norton's theorem to replace Vig, Rig and Rin with a signal current source and an equivalent parallel resistance. Show that by selecting Rig = R, the equivalent parallel resistance becomes infinite and the current I, into the load impedance Z, becomes Vrig /R Rig +2 Vas R R Figure (Q1)
