I've been looking through problems for a final review study and ran across a problem that I'm struggling a bit with. I'm supposed to find Av and Gv for the enhancement PMOS shown in the attachment. The problem I'm having is drawing it in H parameter form. I've never drawn a PMOS in small signal analysis before and I haven't been able to find examples online. Do you just switch the direction of the arrow for gmVGS? I attached what I think it should look like but I'm not sure. Could someone verify my work? Thanks.

 

Have a look here:

Also, the signal source is not a the input side but at the output side.

 

I drew it at the output. I just moved it over to the left side. Notice that I have it in parallel with Re and left out R1 and R2 since they are bypassed.

 

nvm that is a nmos rather than a pmos apparently so I figured it out. Thanks anyways
