Abstract
An internal supply voltage generation circuit includes first and second driving circuits and a resistive device. The first driving circuit receives a feedback voltage from a first node and generates a first output voltage based on first and second reference voltages to provide the first output voltage to the first node. The first output voltage is maintained between the first and second reference voltages. The second driving circuit receives a feedback voltage from a second node voltage and generates a second output voltage based on third and fourth reference voltages to provide the second output voltage to the second node. The second output voltage is maintained between the third and fourth reference voltages, and the second output voltage of the second node is provided as an internal supply voltage. The resistive device is coupled between the first and second nodes.
