For the BJT in the amplifier shown below, VBE=0.7 V, kT/q=26 mV. Assume that BJT output resistance (ro) is very high and the base current is negligible. The capacitors are also assumed to be short circuited at signal frequencies. The input vi is direct coupled. The low frequency voltage gain vo/vi of the amplifier is
