Abstract
A layout of a voltage/current reference system is disclosed. A first voltage/current reference circuit (for example, a bandgap reference circuit) and a second voltage/current reference circuit are respectively laid out on either side of a substrate, such as edges or perimeter sides of the substrate. A reference voltage/current is derived by averaging respective output reference voltage/current values of the first and the second voltage/current reference circuits. Accordingly, the noise influence on the voltage/current reference system is minimized.
