Hi,
How do i go about finding the Q-Point of the above Circuit.
Vtp = -1v, lamda is 0.01V^-1
Kp = 0.5mA/V^2
btw the Veq should be 1V.
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 5.317v and -1.317v. it seems that my Vgs is wrong..
Vds for -1.317 is -9.87V, Id = 25.12uA
cos for both value of Vgs, |Vgs|>= |Vtp|
and both answer are in saturation region |Vds|>= |Vgs|-|Vtp|
Btw to find Vds can i do by using this equation
Vdd-IdRs-Vsd-IdRd-Vss=0
