I want you make a amplifier with 500 voltage gain and use a amplifier with common emitter, but I can't get a gain over the 100 with any value of resistors. Vdd is 12 V and b is 100

 

Use an op-amp.

 

Expecting 500 gain from a single BJT is unrealistic, you need at least two stages.

 

A single transistor with high gain produces severe distortion at fairly high levels.

 

And that is at a gain of 140. I don't think you can get to 500 with even with severe distortion.

 

Also read up about the concept of gain-bandwidth product.
