bandgap reference layout
hi all
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:
a)the cascoded current mirror(which consist of pmos)
b)the opamp
c)diode
d)resistors
for this bandgap circuit i realy appreciate it
thank you
