Abstract
An embodiment circuit includes a first voltage divider coupled between a first voltage level and a ground potential. The circuit further includes an error amplifier having a first input terminal coupled to a node between a first resistive element and a second resistive element of the first voltage divider. The circuit further includes a second voltage divider coupled between a second voltage level and a reference voltage, wherein a second input terminal of the error amplifier is coupled to a node between a third resistive element and a fourth resistive element of the second voltage divider, and wherein an output voltage of the error amplifier is configured to control a potential difference between the first voltage level and the second voltage level.
