1. hejå

36 and -48

@heja Here, VS=90V, R=1kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=3V. What is the dc operating point (bias) output voltage VOUT (in Volts) of this amplifier?

3. natasha5336

plz mention formulas @heja

4. chanakya2346

plz mention formulae @heja

5. 1431mahi

Here, VS=100V, R=1kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=4V.

@hejå pls let us kno the formulas

7. chanakya2346

VS=80V, R=3kΩ, and the transistor parameter f=2mAV3. The amplifier is biased with VIN=2V. What is the dc operating point (bias) output voltage VOUT (in Volts) of this amplifier?

8. chanakya2346

plz reveal the formula

9. hejå

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

@hejå this is q.4 plz answer 5

11. machu

Mine is VS=100V, R=5kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=2V.

12. hejå

ok give me 2 minutes to go thru my paper work and find the formula haha

@hejå deary i used up a submittion

@chanakya2346 did u solve the question

15. chanakya2346

see u guys later gotta go ok...i n an hr

17. chanakya2346

@hejå have u found the formula in your paper work

18. natasha5336

plz reveal the formulas heja

19. hejå

VS=100V, R=5kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=2V. 60What is the small signal gain (vOUTvIN) of this amplifier when it is biased as above? -60

20. machu

bingo! right on the spot! thanks heja

21. Nurali

@heja What is the dc operating point (bias) output voltage VOUT (in Volts) of this amplifier?

22. chanakya2346

@hejå formulas plz

23. akash97

@hejå : VS=80V, R=1.5kΩ, and the transistor parameter f=2mAV3. The amplifier is biased with VIN=2V. give me ans or formula plz

24. 1431mahi

@heja Here, VS=100V, R=1kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=4V. What is the dc operating point (bias) output voltage VOUT (in Volts) of this amplifier? unanswered What is the small signal gain (vOUTvIN) of this amplifier when it is biased as above?

25. natasha5336

@heja plzz give us formulae

26. chanakya2346

@heja formula????????????????

@heja pls atleast tell me your question pls...

28. chanakya2346

@heja plz post some something(either formula or u r question)

@hejå ere, VS=90V, R=1kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=3V. What is the dc operating point (bias) output voltage VOUT (in Volts) of this amplifier? incorrect

30. machu

chanakya..ur gain mayb -72 ....i think i saw someone post it smewher

31. natasha5336

32. natasha5336

i think its correct

@natasha5336 of what

34. Nurali

Here, VS=100V, R=1kΩ, and the transistor parameter f=1mAV3. The amplifier is biased with VIN=4V.

35. 1431mahi

any one mine plzzzzzzz

36. chanakya2346

ty @machu got it ri8

@machu , @natasha5336 , @chanakya2346 , @saadixyz Here, VS=80V, R=3kΩ, and the transistor parameter f=2mAV3. The amplifier is biased with VIN=2V. wats the answer pls lemme kno

38. 1431mahi

@Nurali we got the same question if u know the ans plzz help me

39. chanakya2346

40. natasha5336

@saadixyz and gain =-27 check it

41. chanakya2346

have u got it ri8 @kaddy

42. chanakya2346

@kaddy have u done with this (dc operating point (bias) output voltage VOUT (in Volts) of this amplifier?)

43. benzo

what is b

closing this question of moving to next question RAP IT GUYS

@chanakya2346 32 i think so....check it

46. chanakya2346

one submission left for me (@kaddy r u sure with the ans)

47. 1431mahi

yes i hope so....

49. chanakya2346

ha ha ha @kaddy i got it man

50. benzo

heja what is b in the formula Here, VS=80V, R=3kΩ, and the transistor parameter f=2mAV3. The amplifier is biased with VIN=2V.

51. machu

52. benzo

32 and -72 people thats good

53. benzo

Q1....1 to 7 ?

54. rocky987

@natasha5336 pls lemme kno d formula

56. akash97

@benzo : for ach data u get 32 & -72

@chanakya2346 :)

58. akash97

@natasha5336 : plz tell d formulas

59. benzo

yes look at my q and now the answer

60. benzo

akash its good

61. akash97

@benzo : tell me d formulas yar

62. rocky987

32 and -72 are wrong answers

63. petrucci

@benzo Vout=32 and gain = -72

64. lucky12345

@petrucci plz tell the formula

65. akash97

@petrucci : do u have formulas for dat??????????

66. benzo

heja what is b in the formula Here, VS=80V, R=3kΩ, and the transistor parameter f=2mAV3. The amplifier is biased with VIN=2V. its good for me

67. petrucci

@ akash97 Q. 5. Vout=Vs-(f*(Vgs^3))*RL Gain = -3*f*(vgs^2)*RL

68. akash97

@petrucci : value of vgs????????

69. petrucci

Akash97 Its the VIN itself

70. akash97

@petrucci : ty

71. petrucci

@benzo just put the values i gave....ur values are same with me..

72. benzo

pet u got it q1

73. jayapavan
