Hi,

How do i go about finding the Q-Point of the above Circuit.



i do by Vdd-IsRs+Vgs-IgReq-Veq=0
and Ig =0A so Is=Id

equation can be broken down into
Vdd-IdRs+Vgs-Veq=0

What i get for Vgs is 5.873v and -1.873v. it seems that my Vgs is wrong..

Btw to find Vds can i do by using this equation
Vdd-IdRs-Vsd-IdRd-Vss=0

Anyone could help me see what i did wrong.
