Abstract
A mid supply reference generator (100, 200, 300) has a first resistance element (106, 206) coupled to a first supply. A second resistance element (108, 208) is coupled to a second supply. A third resistance element (110, 210) is coupled to the second supply A first transistor element (116, 216) is coupled to the first resistance element and the second resistance element, the first transistor element coupled between the first and second resistance element such that the first and second resistance elements provide a reference voltage drop from the same current level. A second transistor element is (120, 220) coupled between the first supply and the mid supply output, the second transistor element to drive the output providing a desired mid supply potential. A third transistor element (118,218) is coupled to the mid supply output and to the third resistance element, the third transistor element and the first transistor element being connected such that they generate proportional currents.
