摘要：
An on-chip voltage conversion apparatus for integrated circuits includes a first capacitor; a first NFET device configured to selectively couple a first electrode of the first capacitor to a low side voltage rail of a first voltage domain; a first PFET device configured to selectively couple the first electrode of the first capacitor to a high side voltage rail of the first voltage domain; a second NFET device configured to selectively couple a second electrode of the first capacitor to a low side voltage rail of a second voltage domain, wherein the low side voltage rail of the second voltage domain corresponds to the high side voltage rail of the first voltage domain; and a second PFET device configured to selectively couple the second electrode of the first capacitor to a high side voltage rail of the second voltage domain.
