Hi, how can i amplify 2v to 10v. (with 4MHz freq)

 

Use an op amp? Just search op amp gain on google and you will see the circuit - very common. Just make sure you know what the output load. Why do you want to do this and is the 2V already at a 4MHz frequency?

 

Even a single transistor can be used. Hard to tell without specs or details.

pfft... who needs details anymore.. Aren't we all mind readers by now

 

There's the complete schematic!

 

Excuuuuuze me where did you get that from? That is the very same computer aided design tool I use with all my designs.......
