Question

question 6-The circuit elements have the following values: Vin=15V, R1=0.5Ω, R2=1.5Ω, R3=5Ω, A=2 and B=1.5!!!! anwers pls?????

Answer 1

i1=Vo/(R3-B*R1*R3)
Vo=Vin(R3-B*R1*R3)/(R3-(B*R1*R3)+R1+R2+AR2)
Vth=Vo

Answer 2

question 1
question 1-

1) (R*b)/(1+R*b)*vIN
2) (VS*(1+R*b)-vIN)/(1+R*b)
current through R1 =current through R2 =(V1-R3(I1-I2))/(R1+R2+R3)
current through R3 =(V1-(R1R2)(I1-I2))/(R1+R2+R3)
1. Va=(current through R2)*R2+Vb
2. Vb=(current through R3 )*R3
3. power in R1= current through R1*current through R1*R1
4. power in R2=current through R2*current through R2*R2
5. power in R3=current through R3*current through R2*R3
6. power in V1=V1*current through R1
7. power in i1=Vb*current through R3
8. power in i2=-Vb*current through R3


question 2

refer week 3 hw 3 q1

question 4

1. (R*b)/(1+R*b)*vIN
2. (VS*(1+R*b)-vIN)/(1+R*b)

Question 5

Vgs=Vin

1) Vout=Vs-(f*(Vgs^3))*R
2) Gain = -3*f*(vgs^2)*R

question 6
1)Vo* (R3-(B*R1*R3)+R1+R2+A*R2)/(R3-B*R1*R3)=VIN
2)i1=V0/(R3-B*R1*R3)
3)vo = vth
4)Rth=Vth/Isc
