Unformatted text preview: 2 of 2. (a) Draw and label the hybrid-π 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 π and r . Answer: See class notes. (b) How is the hybrid-π 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 π in the i b branch with r e in the i p e branch such that i b r π = i p e r e . 1...
