Hi everyone,

I have this following problem (uploaded it in the pdf). I have made an attempt at solving it, but now i am just stuck.

I have done question one, and have confirmed my answers in PSpice.

my Id = 16uA, Vgs = 1.4V and Vds = 4.6V ( 3 + 8/5)
and for p-channel the values are just opposite.

My problem is that i am stuck on question 2 where i have to calculate Vout min, Vout max, Vin min, Vin max. I thought that Vout max is Vdd - Vod, but i seem to be wrong.

Any help will be very much appreciated.

Kind Regards
Kash

For the transistor model you are using, what are you defining the boundaries of the saturation region to be?
