MCQ (Single Correct Answer)

-0.6

A bipolar transistor is operating in the active region with a collector current of 1mA. Assuming that the 'β' of the transistor is 100 and the transconductance (g_m) and the input resistance ($${r_\pi }$$) of the transistor in the common emitter configuration, are

g_m = 25 mA/V and $${r_\pi }$$ = $$15.6\,\,k\Omega $$

g_m = 40 mA/V and $${r_\pi }$$ = $$4.0\,\,k\Omega $$

g_m = 25 mA/V and $${r_\pi }$$ = $$2.5\,\,k\Omega $$

g_m = 40 mA/V and $${r_\pi }$$ = $$2.5\,\,k\Omega $$
