Question 225: Semiconductors and Logic Gates

Question

In an experiment of CE configuration of n-p-n transistor, the transfer characteristics are observed as given in figure.
If the input resistance is 200 $$\Omega$$ and output resistance is 60 $$\Omega$$, the voltage gain in this experiment will be ____________.

Accepted Answer

Voltage gain $$ = {{{I_C}{R_0}} \over {{I_B}{R_i}}}$$
$$ = {{(10\,mA)(60\,\Omega )} \over {(200\,\mu A)(200\,\Omega )}}$$
$$\Rightarrow$$ Voltage gain = 15
