Electronics question , please help?
is it possible to get the voltage gain in an fet small signal analysis without vp
example if the yos =40micro simiens
Idss=8mA
vgs(off)=-4V
RG=10 Mega ohms
RD=2.2 KILO ohms
RS=750 ohms
and capacitor 1 is 0.05 micro farad and capacitor 2 is 0.05 micro farad.can you guy help me to calculate for VP..please?

Assuming small signal conditions and the frequency is high enough that capacitors act as short circuits. (you didn't specify a frequency)
Vgain = (2*RD*Idss)/Vp)
Vp = vgs(off)
Vgain = [2*(2.2E3)*8E-3]/-4
Vgain = -8.8
