HW 4 material

Question 1

Given a circuit like this, how do you find V_out?

Answer 1

1) Find “loops” related to V-, V+, and V_out
2) Simplify and combine until you get an expression for V_out that does not contain V+ or V-

Question 2

In a negative feedback loop what are the golden rules?

Answer 2

1) V+ = V-
2) I+ = I- = 0
3) V_out between +-15V
