GATE Electronics and Communications (EC) 2017 Shift 1 Solved Paper

For the DC analysis of the Common-Emitter amplifier shown, neglect the base current and assume that the emitter and collector currents are equal. Given that V_T = 25 mV, V_BE = 0.7 V, and the BJT output resistance r_o is practically infinite. Under these conditions, the mid-band voltage gain magnitude, ${\mathit{A}}_{\mathit{v}}=\frac{{\mathit{V}}_0}{{\mathit{V}}_{\mathit{i}}}$V/V is ________.
