Hi everyone!

I'm trying to set up a small signal model of a common source stage. I have some questions regarding components I like to use in the schematic. These are the package I use and some general settings.

\draw (-3,1) to[open,v=$U_{in}$] (-3,0); <-- this gives me an arrow I don't want.

\draw (0,0) to[cI] (0,1);                <-- I want to resize this component.
\draw (1,1) to[R=$R_D||r_0$] (1,0);

1. Where do I find information of how the [open, ...]-edge can be altered?
2. Is it possible to resize the current source?

The voltage drop seems to be an European - North American thing. So, that's solved. The sizing though, still a problem...
