In the circuit of let VCC 5 2VEE 5 6 V, RC1 5 RC2 5 10 kV, IEE 5 0.45 mA, and REE 5 `, and let the BJTs be mismatched, with Q1’s emitter area being 25% larger than Q2’s. (a) If vI1 5 vI2 5 0, fi nd iC1, iC2, and vOD (assume negligible base currents). (b) If vI2 5 0, fi nd the value of vI1 that will drive vOD to zero. (c) If vI1 5 vI 2 5 0, fi nd DR such that raising one of the collector resistances (which one?) to (10 kV 1 DR) while simultaneously lowering the other to (10 kV 2 DR) will result in vOD 5 0. What are the collector voltages now?
