Hello, I am building a Common source amplifier as shown bellow.
As you can see bellow The Vsource signal is good sinus.
but after the capacitor the sinus is totally canceled and i got only the DC bias.
I am supposed to see the sinous with DC offset after the C2 capacitor.
Where did i go wrong?
Thanks.

 

C1: 1/(2 * PI * 10000Hz * 1pF) = 15.9M Ohms
L1 : 2 * PI * 1000Hz *1nH =6.28E-5 Ohms
