4. The transistor in the amplifier below has been biased such that IC - 0.3mA (no need to do DC analysis). = 10V Bo + 8m o C 10ΚΩ o Vo (a) - С 10ΚΩ ẞ =100 Bib 83Ω Rin (b) i) Find the small signal voltage gain (vo/vi) using the BJT small signal model shown in Fig. a) ii) Repeat with the model in Fig. b). Which do you prefer for this circuit? iii) What is the input resistance, Rin, of the amplifier? How does this value compare with that of a MOSFET? What happens when you make the emitter resistance zero?
