From EE 322 Course (Electronics II)

All questions refer to a "simplified" CE amplifier that has no RE at all, and no C3. You'll need to write down the information in this introduction to use throughout the quiz The other components are: R 100 2, RB 200 k2, Rc 5 k2, R3 10 k2. The amplifier has input and output coupling capacitors C C2 10 H There is no CL. The bias circuit gives Ic 1.5 mA. The transistor has B 120, r 50 ks2, cu 2 pF and C 12 pF. You can neglect r Answers are given to 3 significant figures only, which should cover simple rounding differences. Carry a couple more decimal places through your calculations, then round off at the end.

Explanation / Answer

1) Req= parallel combination of R1 and R3 =99.000 ohms

c1=10 micro farad

therefore the short circuit time constant =RC=.9ms

Hence option 3 is correct.
