What are the 20 best electrical and electronic engineering European universities?

You ask a bit much.

The English language master program at TU Dresden in organic and molecular electronics is certainly outstanding. It's a so called German "university of Excellence", widely called elite university within Germany, and Dresden represents Europe's biggest cluster of microelectronics. It's ahead in material sciences.

The "CHE University Ranking 2012/13" sees TU in the lead among German universities in electronics and information technology.
