Question

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.

Vgain = (2*RD*Idss)/Vp)

Vp = vgs(off) 

Vgain = [2*(2.2E3)*8E-3]/-4
Vgain = -8.8

You need to give a link to the schematic.
