Integrated circuits with bi-directional charge pumps |
摘要 |
A method includes receiving a first voltage at a first input circuit of a bi-directional charge pump circuit, selectively turning on a first switch of a switching circuit that is coupled electrically to a deep N-well transistor of a first set of one or more intermediate pump stages that are coupled between the first input circuit and a first output circuit, and providing a third voltage from the first output circuit in response to receiving a second voltage at an input of a first diode of the output circuit from the first set of the one or more intermediate pump stages. |

1. A method, comprising:
receiving a first voltage at a first input circuit of a bi-directional charge pump circuit; selectively turning on a first switch of a switching circuit that is coupled electrically to a deep N-well transistor of a first set of one or more intermediate pump stages that are coupled between the first input circuit and a first output circuit; providing a third voltage from the first output circuit in response to receiving a second voltage at an input of a first diode of the output circuit from the first set of the one or more intermediate pump stages; receiving the third voltage at a second input circuit of the bi-direction charge pump circuit; selectively turning on a second switch of the switching circuit that is coupled electrically to a deep n-well transistor of a second set of one or more intermediate pump stages that are coupled between the second input circuit and a second output circuit; and outputting a negative pump from the second output circuit in response to receiving a fourth voltage from the second set of one or more intermediate pump stages. |
