Question

plzzz help me Q6
The circuit elements have the following values: Vin=18V, R1=1.5Ω, R2=3Ω, R3=4Ω, A=1.5 and B=0.5.

What is the value of the current i1 (in Amps)?
What is the value of the output voltage vOUT (in Volts)?
We wish to create a Thevenin equivalent model of the above shown circuit as seen from its Output Port.

What is the value of the Thevenin equivalent voltage as seen from the Output Port (in Volts)?
What is the value of the Thevenin equivalent resistance (in Ohms) as seen from the Output Port?

Answer 1

i1=1.8
vOUT=1.8
Vth=1.8
Rth=3.6

Answer 2

neelima plz help me too, plz send the formula.

Answer 3

i1=vOUT/(R3-(B*R1*R3))
vOUT=Vin(R3-(B*R1*R3))/(R3-(B*R1*R3)+R1+R2+(A*R2))
Vth=vOUT
Rth=Vth/Isc
where Isc=Vin*(1-(B*R1))/((A*R2)+R1+R2)

Answer 4

Vin=45V, R1=1.5Ω, R2=2Ω, R3=6Ω, A=2 and B=0.5.

Answer 5

neelima can u calclulate for me?

Answer 6

i1=5
vOUT=7.5
Vth=7.5
Rth=5

Answer 7

Thanku neelima

Answer 8

Q1
R1=50Ω, R2=50Ω, R3=100Ω, V1=4V, I1=0.0001A and I2=0.001A
(a) What is the value of voltage vA in Volts?
(b) What is the value of voltage vB in Volts?
Now let us determine if the answers you came up with satisfy the laws of physics.

What is the power (in Watts) dissipated in resistor R1?
What is the power (in Watts) dissipated in resistor R2?

What is the power (in Watts) dissipated in resistor R3?

Answer 9

Neelima Plzzz help me again

Answer 10

vA = (R2*V1 + R3*V1 + I1*R1*R3 - I2*R1*R3)/(R1 + R2 + R3)
vB = (R3*(V1 + I1*R1 + I1*R2 - I2*R1 - I2*R2))/(R1 + R2 + R3)
Power for R1 = (vA-V1)^2/R1
Power for R2 = (vA-vB)^2/R2
Power for R3 = vB^2/R3
Power for V1 = V1 * (V1-vA)/R1
Power for I1 = V1 * I1
Power for I2 = V1* (-I2)

Answer 11

Q2
VS=5.0V, VOH=4.5V, VIH=4.0V, VIL=1.5V, VOL=1.0V.
What is the low noise margin (in Volts)?
What is the high noise margin (in Volts)?
What is the width of the forbidden region (in Volts)?
Suppose that the threshold voltage for the MOSFET is VT=2.0V and RON=16000.0Ω.
What is the minimum value of the pullup resistor RPuI (in Ohms) for which this inverter can obey the required static discipline?
Now, consider the NAND gate of this family. What is the minimum value of the pullup resistor RPuA (in Ohms) for which this inverter can obey the required static discipline?
How about the NOR gate of this family. What is the minimum value of the pullup resistor RPuO (in Ohms) for which this inverter can obey the required static discipline?
Assume that we implemented this family with the minimum pullup resistors that you have already calculated.
What is the maximum power (in Watts) consumed by the inverter?
What is the maximum power (in Watts) consumed by the NAND?
What is the maximum power (in Watts) consumed by the NOR?

Answer 17

@apurvdixit713
What is the maximum power (in Watts) consumed by the inverter?
Answer : Power = (Vs^2)/ (Rpull + Ron total)

What is the maximum power (in Watts) consumed by the NAND?
Answer : Power = (Vs^2)/ (Rpull + 2*Ron total)

What is the maximum power (in Watts) consumed by the NOR?
Answer : Power = (Vs^2)/ (Rpull + Ron||Ron)

Answer 18

Ron =v Ron total . . for you its 16000

Answer 19

Ron = Ron total . . . 16000
