1. For the following Op Amp circuit (assume an ideal Op Amp)

1. What is the overall gain, v_o/v_i, of this amplifier?

As a guide to solving this problem, a methodical application of Op Amp golden rules and basic nodal analysis is all that’s needed. Supply answers (which may be either numerical or formulas) for each of the questions below, which should produce the desired solution.

1. What is the voltage at the inverting input terminal of the op amp?

1. What is the current i₁ ?

1. What is the current i₂ ?

1. What is the voltage at node x ?

1. What is the current i₃ ?

1. What is the current i₄ ?

1. What is the output voltage, v₀ ?

1. And, finally, what is the ratio: v₀/v_i ?
