Use $\beta = 100$ and $V_A = 100\text{ V}$ for all transistors when calculating gains. However, assume ideal current mirrors $ - $ i.e., don't worry about $\beta$ or $V_A$ corrections when calculating the currents. Also, assume $\alpha = 1$ for DC calculations, and don't worry about $V_{CE}$ when finding $r_o$. Otherwise, use the best (most accurate) equations we have with the information available $ - $ don't make other unnecessary approximations. Given: $I_{ref} = 1\text{ mA}$, $I$ in $Q_6 = 1\text{ mA}$, $R_t = 1\text{ k}\Omega$. Use absolute values for all gains. Ignore the equivalent resistance of the diodes. Be very careful that you use the correct currents and small-signal parameters in each branch. Fill free to check those numbers before continuing. a) Describe in a few words the function of each transistor in this circuit. I'm looking for things like \"differential amplifier input stage\", for example. b) What are the currents in $Q_2$ and $Q_5$, respectively? c) What is the differential gain of the first stage? d) What is the gain of the second stage?
