Hi everyone,
I need to find the voltage gain for the following scheme:
My book says I need to calculate 'id' first, which is:
id = gm.ro.vin/(Rs+RL+ro+(gm.ro.Rs))
Then with the help of vout = -RL.id you get:
Av = -gm.ro.RL/(Rs+RL+ro+(gm.ro.Rs))
So I get the last part, but I really have no clue how I get to 'id'...
Could anyone help me with this? Give me some more steps.. (my book only shows the above formulas).
Thanks!
