In the following transistor circuit, V_BE = 0.7V, r_e = 25m/I_E, $$\beta $$ and all the capacitances are very large.

The Value of DC current I_E is

In a transconductance amplifier , it is desirable to have

For the BJT circuit shown, assume that the $$\beta $$ of the transistor is very large and V_BE = 0.7 V. The mode of operation of the BJT is

In the transistor amplifier circuit shown in the figure below, the transistor has the following parameters: $${\beta _{DC}}$$ = 60, $${V_{BE}}$$ = 0.7V, $${h_{ie}} \to \,\,\infty $$, $${h_{fe}} \to \,\,\infty $$. The capacitance C_C can be assumed to be infinite.

The small-signal gain of the amplifier $${{{V_c}} \over {{V_s}}}$$ is
