7.57 Design an amplifier using the configuration of Fig. 7.30(a). The power supplies available are ±5 V. The input signal source has a resistance of 50 , and it is required that the amplifier input resistance match this value. (Note that R in = re RE re.) The amplifier is to have the greatest possible voltage gain and the largest possible output signal but retain small-signal linear operation (i.e., the signal component across the base–emitter junction should be limited to no more than 10 mV). Find appropriate values for RE and RC. What is the value of voltage gain realized from signal source to output?
