Consider the differential amplifier shown below with RB = 50K and Rc = 10K2 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 would be the max common mode voltage that can be applied? [Hint: Q1 and Q2 must remain in saturation and common mode voltage causes current in Q3 to increase] IOV RB Q4 Vin Re QI Q3 Rc Nc -10V
Close to 10V O b. Less than 5V O C. close to 15V O d. Close to 8V a.
