Question

Consider the circuit shown here, vd and vc are small signal sources. VCC, VEE, and 10 are DC sources. The two transistors are identical. Select all the statements below that are true about this circuit in DC analysis. VB1 = VB2 VC1 = VC2 VE1 = VE2 = - VEE VB1 = 0 We now consider the circuit in AC analysis. We will use superposition. In this question we will consider the case when vd = 0. Determine vo. Your Answer: Answer Now consider the case when vc = 0. vd = 5 mV. 10 = 1 mA. R = 5k. Beta = 100. Determine vo. Hint: I have given you here the values of 10 and beta, so you will need to calculate gm and draw the small signal equivalent circuit to do calculations. Your Answer: Answer

Explanation / Answer

question1

1.VB1=VB2

2.VC1=VC2

only two stetment are correct

(2) when vd=0 at that time vo=vcc-vc
