8.59 Asmentioned in the text, the CB amplifier functions as a current buffer. That is, when fed with a current signal, it passes it to the collector and supplies the output collector current at a high output resistance. Figure P8.59 shows a CB amplifier fed with a signal current isig having a source resistance Rsig = 10 k. The BJT is specified to have β = 100 and VA = 50 V. (Note that the bias arrangement is not shown.) The output at the collector is represented by its Norton equivalent circuit. Find the value of the current gain k and the output resistance R out. Note that k is the short-circuit current gain and should be evaluated using the T model of the transistor with the collector short-circuited to ground.
