guys, i need some help...
i'm looking for a voltage-controlled current source...
i found this: http://electronicdesign.com/Articles/ArticleID/9018/9018.html"
but when i try it for a maximum current of 500mA (using LM324N for the opamp and 2N2222 for the transistor), it doesn't work...
help me pls...
