Chapter 11, Problem 11.8P

Consider the circuit in Figure P11.8, with transistor parameters: $\beta =100$ $V_{BE}(\text{on})=0.7\text{V},$ and $V_A=\infty .$ (a) For $v_1=v_2=0,$ find $I_{C1},I_{C2},I_E,V_{CE1}$ and $V_{CE2}$ (b) Determine the maximum and minimum values of the common-mode input voltage. (c) Calculate $A_d$ for a one-sided output at the collector of $Q_2$ .
