Feedback in Figure-1:
The feedback in Figure-1 is negative feedback.
Given Values:
Rc1 = 3KΩ
Rc2 = 500Ω
RE = 50Ω
Rs = Rf = 1.2KΩ
hfe = 50
hie = 1.1KΩ
hre = hoe = 0
Overall Voltage Gain (Avf):
The overall voltage gain (Avf) can be calculated using the formula:
Avf = - (Rf / Rs) * (Rc2 / Rc1)
Here, Rf = Rs = 1.2KΩ, Rc2 = 500Ω, and Rc1 = 3KΩ.
Avf = - (1.2KΩ / 1.2KΩ) * (500Ω / 3KΩ)
= - (1) * (0.1667)
= -0.1667
Therefore, the overall voltage gain (Avf) is -0.1667.
Overall Current Gain (Aif):
The overall current gain (Aif) can be calculated using the formula:
Aif = - (hfe / (1 + hfe * (Rc2 / RE)))
Here, hfe = 50, Rc2 = 500Ω, and RE = 50Ω.
Aif = - (50 / (1 + 50 * (500Ω / 50Ω)))
= - (50 / (1 + 50 * 10))
= - (50 / (1 + 500))
= - (50 / 501)
≈ -0.0998
Therefore, the overall current gain (Aif) is approximately -0.0998.
Input Impedance (Rif):
The input impedance (Rif) can be calculated using the formula:
Rif = hie / (1 + hfe * (Rc2 / RE))
Here, hie = 1.1KΩ, hfe = 50, Rc2 = 500Ω, and RE = 50Ω.
Rif = 1.1KΩ / (1 + 50 * (500Ω / 50Ω))
= 1.1KΩ / (1 + 50 * 10)
= 1.1KΩ / (1 + 500)
= 1.1KΩ / 501
≈ 2.1956Ω
Therefore, the input impedance (Rif) is approximately 2.1956Ω.
Output Impedance (Rof):
The output impedance (Rof) can be calculated using the formula:
Rof = (Rc1 || (Rc2 / (1 + hfe))) + RE
Here, Rc1 = 3KΩ, Rc2 = 500Ω, hfe = 50, and RE = 50Ω.
Rof = (3KΩ || (500Ω / (1 + 50))) + 50Ω
= (3KΩ ||
The feedback in Figure-1 is negative feedback.
Given Values:
Rc1 = 3KΩ
Rc2 = 500Ω
RE = 50Ω
Rs = Rf = 1.2KΩ
hfe = 50
hie = 1.1KΩ
hre = hoe = 0
Overall Voltage Gain (Avf):
The overall voltage gain (Avf) can be calculated using the formula:
Avf = - (Rf / Rs) * (Rc2 / Rc1)
Here, Rf = Rs = 1.2KΩ, Rc2 = 500Ω, and Rc1 = 3KΩ.
Avf = - (1.2KΩ / 1.2KΩ) * (500Ω / 3KΩ)
= - (1) * (0.1667)
= -0.1667
Therefore, the overall voltage gain (Avf) is -0.1667.
Overall Current Gain (Aif):
The overall current gain (Aif) can be calculated using the formula:
Aif = - (hfe / (1 + hfe * (Rc2 / RE)))
Here, hfe = 50, Rc2 = 500Ω, and RE = 50Ω.
Aif = - (50 / (1 + 50 * (500Ω / 50Ω)))
= - (50 / (1 + 50 * 10))
= - (50 / (1 + 500))
= - (50 / 501)
≈ -0.0998
Therefore, the overall current gain (Aif) is approximately -0.0998.
Input Impedance (Rif):
The input impedance (Rif) can be calculated using the formula:
Rif = hie / (1 + hfe * (Rc2 / RE))
Here, hie = 1.1KΩ, hfe = 50, Rc2 = 500Ω, and RE = 50Ω.
Rif = 1.1KΩ / (1 + 50 * (500Ω / 50Ω))
= 1.1KΩ / (1 + 50 * 10)
= 1.1KΩ / (1 + 500)
= 1.1KΩ / 501
≈ 2.1956Ω
Therefore, the input impedance (Rif) is approximately 2.1956Ω.
Output Impedance (Rof):
The output impedance (Rof) can be calculated using the formula:
Rof = (Rc1 || (Rc2 / (1 + hfe))) + RE
Here, Rc1 = 3KΩ, Rc2 = 500Ω, hfe = 50, and RE = 50Ω.
Rof = (3KΩ || (500Ω / (1 + 50))) + 50Ω
= (3KΩ ||
