Question The figure below shows a bipolar current mirror where the current through the resistor is denoted as Iref and the two transistors, Q1 and Q2 have emitter areas of AE and A2 respectively. Both transistors have the same Early voltage VA and same current gain ß. The power supply, Vad 10V and assume VBE = 0.7V. 1. For each of the five cases mentioned below, find both the mirror ratio MR = Lour/ref and the ratio of the collector currents Icz/Ici (i.e. there should be 5x2=10 answers). (a) AE2-AE1. B-50, VA-50V. (b) AE2AE1, B-75, V₁=50V. = (c) AE2AEI, B=50, VA=25V. = (d) A2-10AE1. B-50, VA-50V. (e) A2 = 10AE1, B = 75, V₁ = 50V. 2. Based on the above calculations, did you find the mirror ratio to depend on B or VA if the ratio of emitter areas is same? Does the ratio of collector currents depend on ß or VA if the ratio of emitter areas is same? 3. If you assume V (i.e. no Early effect) and B-50, what is the largest mirror ratio you can obtain from this circuit by increasing the ratio of emitter areas (A2/ARI)?
