Consider the differential amplifier shown below with RB = 50KQ and Rc = 10K 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 input impedance of the differential amplifier? O a. close to 50kQ O b. close to 10k O c. Close to 60KQ O d. close to 25kQ O e close to 100KQ
