For the transistor assume that VBE(FA)=0.7 V, VBE(SAT)=0.8 V, Vce(SAT)=0.2 V, VBC(RA)=0.7 V, B=100, B=2, VA=75 V, V=25 mV. a) Determine the Q-point [10] b) Calculate the small-signal parameters of the transistor (gm, re, rn, ro) [5] c) Assume that the capacitors are ideal. Draw the small-signal equivalent circuit. [5] d) Obtain expressions for the input and output resistances, overall voltage gain and then calculate their numerical values. If you could not calculate gm in section (b), in this section take gm=50 mA/V. [10] Vec - 12V Vec - 12V Rc 4.3 kg R CZ 30 ΚΩ Vo 1 uF Rg C 250 0 5uF R 47 ΚΩ R10 ko Ret 2000 CE Rez 1.1 ΚΩ 4.7 uF
