Question
Only a)
Q1. The transistor parameters of Figure 1 are B = 500, Vr = 0.026 V and VBE = 0.7 V. The two transistors are identical. a) What does "the two transistors are identical" mean in the context of circuit analysis and why is this assumption useful? Given Vcc = 13. L, determine the d.c. output voltage at the output terminals vo1 and voz- Note that L is the last digit of your student number. For example, if your number is C1700123, then Vcc = 13.3 V, or if your number is C1700100, Vcс3 13.0 V b) c) Given that the input signal is vi = 2L sin(wt) (mV), determine the total output voltage at terminal vo1- Note that L is the last digit of your student number. For example, if your number is C1700123, then v, = 23 sin(wt) (mV), or if your number is C1700100, v = 20 sin(ot) (mV) Draw the circuit diagram of Figure 1 with both transistors being d) replaced by the Darlington pairs. Explain the main consequence of changing the single transistors by the Darlington pairs. Vcc to 9 kn Vol Voz )/=1.4 mA Figure 1 Differential amplifier
