### Quetions about tikz - circuitikz

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.
\usepackage{tikz} \usepackage{circuitikz}\ctikzset{tripoles/njfet/height=.5}\ctikzset{tripoles/njfet/width=.3}\ctikzset{bipoles/resistor/height=.1}\ctikzset{bipoles/resistor/width=0.3}\ctikzset{bipoles/capacitor/height=.2}\ctikzset{bipoles/capacitor/width=0.1}\ctikzset{monopoles/ground/width=0.15}

The schematic it self looks like this:
\begin{circuitikz}[scale = 0.8, transform shape]  \tiny \draw (-3,1) to[open,v=$U_{in}$] (-3,0); <-- this gives me an arrow I don't want.\draw (-2,1) to[R=$R_1$] (-2,0);\draw (-1,1) to[open,v=$U_{gs}$] (-1,0); <-- unwanted arrow...\draw (0,0) to[cI] (0,1);                <-- I want to resize this component.\draw (1,1) to[R=$R_D||r_0$] (1,0);\draw (2,0)to[open,v_>=$U_{out}$] (2,1);  <-- unwanted arrow...\draw (-3,1) to[short, o-o] (-1,1);\draw (0,1) to[short, -o] (2,1);\draw (-3,0) to[short, o-o] (2,0);\end{circuitikz}

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...
