Chapter 13, Problem 13.15P

Consider the output stage of the 741 op−amp shown in Figure 13.8. Assume ${\upsilon }_1={\upsilon }_2=0$ at the input and assume the bias voltages are $V^{+}=5\text{V}$ and $V^{-}=-5\text{V}$ . Let $I_{\text{REF}}=0.5\text{mA}$ . All other circuit and transistor parameters are described in Example 13.3. Find $I_{C13A},I_{R10},I_{C19},I_{C18},V_{BE19},V_{BE18}$ , and $I_{C14}$ .
