Hi, i have a voltage controlled current source that is being short circuited. What happens if the controlling voltage is not zero?
R1 a R2 c o--/\\/\\/\\---o----/\\/\\/\\----o-------o------o | | | |
- \ / \ \ | V1 / R3,Vab /gVab\ / R4 |
- \\ \\ / \\ | | \\ / | | | | | | o-----------o--------------o-------o------o b d
Here is a rough picture... I'm trying to find the h parameters of this circuit, in particular "h21" where (c,d) is shorted out... In case you want to know....
R1 = 100 ohm R2 = 10e6 ohm R3 = 2.5e3 ohm R4 = 100e3 ohm g = 40 mA/V
Here are the ans. straight from my book.
H11 = 2.6e3 ohm H12 == 2.5e-4 H21 = 100 H22 = 2e-5 conductance
I can get the first two but i'm still working on H21 any help would be appreciated. I general, i dont know how the vcvs behaves when it shorted. Any help would be appreciated.
