Circuit Drawing in Journal And Conference Papers

Hi,
I want to Write a journal and conference papers about RF circuits,
I should use circuit drawing softwares like MIicrosoft Visio or Smartdraw o ... , But Idon't know which softwares are the best one for drawing electronic circuits with high quality and have a full and useful library. Can anyone help about that?
I want really to know Paper writers in RF circuits use which software in their papers.
Thanks alot.

There are some electronic symbol libraries for Adobe Illustrator on the internet.

I am Writing A Journal Paper and I want to know How Designers and Paper writers draw their proposed Circuit In Journal Templates?
Can Anyone who Writes journal papers in Analog Circuits Like RF Circuits Help me?
Thanks alot.

A "super-tool" for drawing schematics doesn't exists. You can use for instance MS Visio and add your own missing symbol. Or you can Latex with packages for electronic symbols (e.g. http://www.texample.net/tikz/examples/circuitikz/) or and own cmdline tool like http://staff.ee.sun.ac.za/pjrandewij...Circuit_Macros.

I prefer MS Visio, it's faster for me!

Personally, I use InkScape instead of Visio because it's free. It doesn't have any good symbols, so I had to make my own. It's okay though—once you've gotten a hang of how to use the software, it's easy to make your own. And if you ever need a new symbol, you can make one that matches your exact style.

I had a professor in college who wrote several textbooks. He drew all his schematics in Paint. PAINT! How painful! But at least his schematics looked good!

This free online tool from Digi-Key make the schematics look like circuits published in electronics magazines:
