Honor Code Statement: I have neither given nor received help on this quiz. Initials 1 of 2. (a) Solve for v o with i o = 0 . (b) Solve for i o with v o = 0 . (c) What is the output resistance r out ? (d) Draw the Thévenin and Norton equivalents at the circuit output. v c = 4 × 5 b 20 - 5 v c 5 5 + 20 = 16 - v c = v c = 8V v o ( oc ) = 4 × 5 b 20 + 5 v c 20 5 + 20 = 16 + 4 v c = 48V v c = 4 × 0 + 5 v c 5 = v c = 0 i ( sc ) = 4 + 5 v c 5 = 4A r out = v o ( oc ) i o ( sc ) = 48 4 = 12Ω

Unformatted text preview: 2 of 2. (a) Draw and label the hybrid- model of the BJT. On the drawings, include labels for the currents i b , i e , i p e , i c , and i p c and labels for the resistors r and r . Answer: See class notes. (b) How is the hybrid- model converted into the T model? Explain any condition that must hold for the models to be equivalent and and draw the T model. Answer: Replace r in the i b branch with r e in the i p e branch such that i b r = i p e r e . 1...
