Baking quality

Is there a way to raise the quality of the baking objects in cycles? I want to bake just a diffuse pass with a single object, but I don’t know how to raise the quality of this bake. Any suggestions?

You can simply increase the size of the UV texture, I had the same problem but couldn’t find a perfect solution. If you have found a solution that is better please respond so that I may have a better way of doing this.
