2. For the follower circuit in Fig. 3, let transistor Q1 has β = 50 and transistor Q2 has β = 100, 
= 5 V, 
= 1 MΩ, I1 = 50 κA, I2 = 5 mA and neglect the Early effect. Use constant voltage drop model of 
= 0.7 V. Thermal voltage 
= 25 mV.
(b) If a load resistance 6201e198c95be. 
= 1 kΩ is connected to the output terminal, find the voltage gain from the base to the emitter of Q2 and the input resistance 6201e1c213cbb.
looking into the base of Q2.
