2. In the following current mirror circuit, Vcc -10V, and the three transistors, Q1, Q2, Q3, have the same saturation current (i.e.,IssIs), and with V for active mode is 0.7V. Then, the three beta values are given by: β91-100, ßQ2-50, and ßQ3-200. The thermal voltage is ντ-25mV. Assuming that you need an output current of i1mA: ref db (a) Find the collector, base, and emitter current for all three Q1 O2 transistors when ia 1mA. (b) Find the refern ie. (c) Find the value of R that provides this reference current. (d) What is the minimum acceptable voltage at the collector of Q2? 2.
