If you have a JPEG image file that you want to use in AutoCAD as a DWG file, you must convert your JPEG file. Unfortunately, there are currently no converter programs that can do a straight JPEG-to-DWG conversion. To convert JPEG to DWG, use a vector converter to convert the JPEG to a DXF file, which is also an AutoCAD file. Then you can use an AutoCAD converter to convert the DXF to a DWG file.
