bandgap reference layout
im designing a bandgap reference with two serial bipolars but im stuck at layout. i need to know a technique for implimenting this circuit , i red that diode ratio must be 8:1 but i dont know the reason. if anyone can help me with designing layout for:
altera VS Xilinx
im doing a project on vhdl that ias IMA_ADPCM compression method usimg VHDL .
there is a code for this algorithm on web but this code uses Xilinx ISE 9.2i tool and i have to use Modelsim Altera web edition .
does anyone can tell me what exactly are diffrences...
synthesis vs simulaton
