I have to build an common source amplifier with JFET whose gain is 3
R load = 4500
R drain = 4500
Vdd = 15 V
RG = 100k
I have to use 2n5457
I used shockley's equation to find IDSS and VGS off . I wonder how do i get the load line to get Q point.
I need to find RS to get ID and plot the load line.
I am stuck at this point.
Besides, I do not want to use bypass capacitor at RS, so what is the gain of the circuit formula?
IS it AV= gm(RD||RL)/(1+ gm(RS))
Any help would be highly appreciated.
thanks
