shows a differential amplifi er variant that uses emitter degeneration. Let VCC 5 2VEE 5 5 V, RC1 5 RC2 5 3.0 kV, RE1 5 RE2 5 120 V, and IEE 5 1.0 mA. (a) If vI2 5 0, fi nd the value of vI1 for which iC1 5 2iC2 (assume negligible base currents). (b) If vI1 5 25 mV, fi nd vI2 so that vOD 5 1.5 V. (c) Using iterations, fi nd vOD if vID 5 100 mV.
