| 摘要 |
The invention relates to a circuit for generating a negative voltage (V-) on the basis of a positive voltage (V+), comprising: at least one first transistor (M1) between a first terminal (12) for applying a potential greater than a reference potential and a first node (15); a first capacitive element (C1) between the first node and a second node (16), a control terminal of said first transistor being linked to the second node; a first switch (K1) between the first node (15) and a second terminal (14) for applying the reference potential; a second switch (K2) between the second node (16) and a third terminal (18) for providing said negative voltage; a third switch (K3) between the second node (16) and the second terminal (14); and a second capacitive element (C2) between the third terminal (18) and the second terminal. |
