CMOS Buffer

Hi,

I need to draw Y as function of A:

I performed the following simulation.
Is it correct?

Thanks.

Looks about right.

Thanks Brownout!

Did I connected the PMOS and NMOS correctly?

I just want to be sure that I got the source and drain connected properly.

Hi,

Yes the simulation looks ok but notice the output only goes down as low as about 4v. That's because without a negative input you cant turn the P channel device on hard enough.

Thank you very much

Notice also the severe crossover distortion, caused by the threshold voltage.
