Top Current Voltage Relationship MCQ Objective Questions

Current Voltage Relationship Question 1:

When the gate to source (VGS) of a MOSFET with threshold voltage of 400 mV, working in saturation region is 1V, the drain current deserved to be 1 mA. Neglecting channel width modulation effect and with assumption MOSFET is in saturation condition, the drain current for an applied VGS of 2V is ______

Answer (Detailed Solution Below) 7 - 7.2

Current Voltage Relationship Question 1 Detailed Solution

Given VT = 0.4 V

In saturation region for VGS = 1 V ID = 1 mA

⇒ ID = K(VGS - VT)2            (assuming k = 1/2 μn Cox)

1 mA = k(1-0.4)2

k=10.36 

For VGS = 2V

ID = K(2 – 0.4)2

=10.36(1.6)2mA 

= 7.11 mA

Current Voltage Relationship Question 2:

When the gate – to – source voltage (VGS) of MOSFET with threshold voltage of 400 mV working in saturation is 900mV, the Drain current is observed to be 1 mA. Neglecting the channel width modulation effects and Assuming that the MOSFET is operating at saturation, the Drain current for an applied VGS of 1400 mV is________ mA

Answer (Detailed Solution Below) 3.9 - 4.1

Current Voltage Relationship Question 2 Detailed Solution

ID=K(VGSVT)2

1mA = K (900 – 400)2

K=1mA/V2104×25

When, VGS = 1400,

ID=1mA25×104V2(1400400)2×V2=1mA×10025×104×104=4mA

Current Voltage Relationship Question 3:

A ideal n-channel MOSFET has following parameters

W=30 μm      μn=450 cm2/V.sec

L=2 μm          tox=350 A

VT=0.80 V      ϵox=3.9ϵo

For a, VDS=3V, the slope (in mA/V) of the plot ID v/s VGS at VGS=3V is _________.

Answer (Detailed Solution Below) 18 - 18.5

Current Voltage Relationship Question 3 Detailed Solution

We have VDS=3V

VGSVT=30.8=2.2 VVDS>VGSVT 

⇒ MOSFET is in saturation.

Current for a MOSFET in saturation is given by

ID=12μnCoxWL(VGSVT)2ID=12μnCoxWL(VGSVT)ID=12μnCoxWLVGS12μnCoxWLVT 

Comparing with y=mx+c

We get, slope of curve m=12μnCoxWL

m=12μnϵoxtoxWLm=12×450×3.9×8.854×1014350×108×302m=18.25 mA/V

Current Voltage Relationship Question 4:

The drain current of a MOSFET in saturation is plotted below.

Gate EC EDC Mock Test Images-Q5

The X and Y axes are

  1. x axisID, y axisVGS
  2. x axisID, y axis(VGSVTH)2
  3. x axisID, y axis(VGSVT)2
  4. x axisID, y axisVGS

Answer (Detailed Solution Below)

Option 3 : x axisID, y axis(VGSVT)2

Current Voltage Relationship Question 4 Detailed Solution

Drain current ID in saturation is given by, ID=12μnCoxWL(VGSVTH)2. So, if we plot ID versus(VGSVTH)2 or ID versus (VGSVTH) , both will result in a linear plot passing through origin.

Current Voltage Relationship Question 5:

For an n-channel MOSFET with a gate oxide capacitance of 3.45x10-7F/cm2, VT=0.6V and W= 25 μm,L= 1 μm. Given, μn=200 cm2/Vs.The drain current at VG= 5V and VD=0.1V is _______mA.

Answer (Detailed Solution Below) 0.74 - 0.76

Current Voltage Relationship Question 5 Detailed Solution

ID={μnCox(WL)[(VGSVT)VDS12VDS2]=(200×3.45×107)×(251)×[(50.6)(0.1)12(0.1)2]ID=7.5×104AID=0.75 mA

For VG = 5V and VD = 0.1V and VT = 0.6V, VDS(0.1V)GS(5V) - VT(0.6V)

∴ Linear region.

Current Voltage Relationship Question 6:

Consider an n-channcl MOSFET with W= 15μm, L= 2μm. and C= 6.9x10-8 Fcm-2. Assume that the drain current in the non-saturation region for VDS= 0.10V is ID= 35μA at VGS= 1.5V and ID=75μA at VGS= 2.5V. The electron mobility is _______.(in cm2/V-s)

Answer (Detailed Solution Below) 772 - 774

Current Voltage Relationship Question 6 Detailed Solution

W=15μm, L=2μm, Cox=6.9x10-8F/cm2

ID1=35μA, VGS1=1.5V

ID1=75μA, VGS1=2.5V

IDn Cox (W/L) (VGS-VT)VDS

ID2-ID1= μn Cox (W/L) (VGS2-VGS1)VDS

(75-35)x10-6 = μn. 6.9x10-8x(15/2)x1x0.1

μn = 772.95 cm2/V-s
