A particular differential amplifier operates from an emitter current source I = 0.4 mA. Each of the collector resistances RC = 20 kΩ and a load resistance RL = 40 kΩ is connected between the two collectors. If the amplifier is fed in the manner shown in Fig. P9.50 with Rsig =100 kΩ find the overall voltage gain. Let β = 100.
