Unformatted text preview: v o as a function of the small-signal input voltage v i . Draw and label any circuits you use to solve for v o . v o = i o ( sc ) r out k R L = 0 . 73 v i 1 2. It is given that v i = 2V , R 1 = 10k , R 2 = 20k , R 3 = 6k , and R 4 = 4k . (a) Solve for the current i . Hint: write a single loop equation through the virtual short circuit. i = v i R 1 + R 3 = 1 8 mA = 0 . 125mA (b) Use the results of the preceding part to solve for v o and the voltage at each of the other 4 nodes in the circuit. v o i ( R 2 + R 4 ) = 3V v + = v = iR 4 = . 5V v R 3 = i ( R 3 + R 4 ) = 1 . 25V v R 1 = v R 3 + v i = 0 . 75V 2...
