Abstract:
1. A circuit comprising: a first switch having a first first-switch end and a second first-switch end; a second switch having a first second-switch end and a second second-switch end; a capacitive device having a first capacitive end and a second capacitive end; a third switch having a first third-switch end and a second third-switch end; a fourth switch having a first fourth-switch end and second fourth-switch end; a switching controller; and a voltage source, wherein the first, second, third, and fourth switches are different from one another; a first node has a first voltage and is coupled to the first fourth-switch end, to the first second-switch end, and to the first capacitive end; a second node has a second voltage and is coupled to the voltage source, to the second fourth-switch end, and to the second third-switch end; a third node is coupled to the second second-switch end, and to the first first-switch end; and the switching controller is configured to selectively open and close the first switch and the second switch such that the first node and the voltage source selectively provide the second voltage.
