Chapter 8, Problem 8.41P

The value of $I_{Biass}$ in the circuit shown in Figure 8.31 is 0.5mA. Assume diode and transistor parameters of $I_{SD1}={10}^{-16}\text{A}$ , $I_{SD2}=4\times {10}^{-16}\text{A}$ , $I_{SQn}=8\times {10}^{-16}\text{A}$ , and $I_{SQp}=1.6\times {10}^{-15}\text{A}$ . For ${\upsilon }_O=0$ and neglecting base currents, determine (a) $V_{BB}$ , (b) ${\upsilon }_{BEn}$ and ${\upsilon }_{BEp}$ , (c) the quiescent collector currents, and (d) the required value of ${\upsilon }_I$ .
