Consider the differential amplifier shown below with RB = 50K2 and Rc = 10KQ and assume the BJT parameters for Q1, Q2, Q3 and Q4 are VA = 70V and B=100. The amplifier is biased with VCC = +10V and VEE = -10V. You may assume VBE = 0.7 when forward biased for all BJTs. What is the common mode output impedance?
