Friends
I need a thermal compensation circuit for control the transistor Ic current. Anyone have a simple circuit for this ? I will put the sensor in the transistor TO-3 case. Thanks, Aldovan |

Take a look here:
http://paginas.fe.up.pt/~fff/eBook/MDA/Mult_Vbe.html http://sound.westhost.com/amp_design.htm#thermal-stab http://www.headwize.com/ubb/showpage...num=3&tid=5688 Also I suggest strongly reading this book: http://www.dself.dsl.pipex.com/ampins/books/book.htm (a whole chapter on thermal compensation and design!) |
