Test: BJT in Amplifier Design - Question 1
Save

Linear amplifier with a gain of 30 dB is fed with 1.0 μW power. The output power of the amplifier

Detailed Solution for Test: BJT in Amplifier Design - Question 1

Test: BJT in Amplifier Design - Question 2
Save

The corresponding maximum input signal permitted is

Detailed Solution for Test: BJT in Amplifier Design - Question 2

If we assume linear operation right to saturation we can use the gain Av to calculate the maximum input signal. Thus for an output swing ∆ Vo = 0.8 we have
∆ Vi = ∆ Vo / Av = -0.7 / -360 = 1.94 mV.

Test: BJT in Amplifier Design - Question 3
Save

(Q.3- Q.5) For the amplifier circuit in Fig. 6.33(a) with Vcc = +10 V, Rc = 1 kΩ and the DC collector bias current equal to Ic

Q. Find the voltage gain.

Detailed Solution for Test: BJT in Amplifier Design - Question 3

Test: BJT in Amplifier Design - Question 4
Save

The maximum possible positive output signal swing as determined by the need to keep the transistor in the active region.
Detailed Solution for Test: BJT in Amplifier Design - Question 4

Assuming the output voltage Vo = 0.3v is the lowest Vce to stay out of saturation.
Vo = 0.3 = 10 – IcRc
= 10 – IcRc + ∆Vo
∆ Vo = -10 + 0.3 + Ic*1.

Test: BJT in Amplifier Design - Question 5
Save

The maximum possible negative output signal swing as determined by the need to keep the transistor in the active region.
Detailed Solution for Test: BJT in Amplifier Design - Question 5

Maximum output voltage before the Transistor is cutoff.
Vce + ∆Vo = Vcc
∆Vo = Vcc – Vce
= 10 – 10 + 10 Ic
= 10 Ic.

Test: BJT in Amplifier Design - Question 6
Save

The transistor in the circuit below is biased at a dc collector current of 0.5 mA. What is the voltage gain?
Detailed Solution for Test: BJT in Amplifier Design - Question 6

Test: BJT in Amplifier Design - Question 7
Save

For a BJt Vt is 5 V, Rc = 1000 ohm and bias current Ic is 12 mA. The value of the voltage gain is __________
Detailed Solution for Test: BJT in Amplifier Design - Question 7

Voltage gain is (Ic X Rc ) / Vt.

Test: BJT in Amplifier Design - Question 8
Save

(Q.8–Q.10) (Q.3- Q.5) For the BJT amplifier circuit with Vcc = +10 V, Rc = 1 kΩ and the DC collector bias current equal to 5 mA,

Q. The value of the voltage gain is _______________
Detailed Solution for Test: BJT in Amplifier Design - Question 8

The voltage is 400 X Ic where Ic is 5 mA.

Test: BJT in Amplifier Design - Question 9
Save

The maximum possible positive output signal swing as determined by the need to keep the transistor in the active region.
Detailed Solution for Test: BJT in Amplifier Design - Question 9

The maximum voltage swing is given by -10 + 0.3 + (Ic X Rc). Putting Ic as 5 mA, we get -4.7 mV.

Test: BJT in Amplifier Design - Question 10
Save

The maximum possible negative output signal swing as determined by the need to keep the transistor in the active region.
Detailed Solution for Test: BJT in Amplifier Design - Question 10

 It is given by -10 + 10 + (Ic X Rc). Putting Ic as 5 mA we get 5V.
