A charge pump (1) for generating a first output voltage (Vo1) between a first output terminal (E) and a reference terminal (D), and a second output voltage (Vo2) between a second output terminal (F) and the reference terminal (D). The charge pump (1) further comprises a first input terminal (C) for inputting a DC voltage (V), a first storage capacitor (Cr1) coupled between the first output terminal (E) and the reference terminal (D) and a second storage capacitor (Cr2) coupled between the second output terminal (F) and the reference terminal (D). The charge pump (1) further comprises a first terminal (A) and a second terminal (B) for coupling a pump capacitor (Cp) to a first triplet of switches (S1, S2, S5) and to a second triplet of switches (S3, S4, S6). The first triplet of switches (S1, S2, S5) selectively couples the first terminal (A) to either the first input terminal (C) or to the reference terminal (D) or to the second output terminal (F). The second triplet of switches (S3, S4, S6) selectively couples the second terminal (B) to either the first input terminal (C) or to the reference terminal (D) or to the first output terminal (E). |
