摘要
Digital CMOS integrated circuit (120) comprising an analog signal processing circuitry with a series of two or more field-effect transistors (FETs). The FETs have a maximum allowed supply voltage value (Vmax). The digital CMOS integrated circuit (120) further comprises a local charge pump (135) for generating an elevated supply voltage (Vsupplydiff) larger than the maximum allowed supply voltage value (Vmax). The local charge pump (135) is arranged such that this elevated supply voltage (Vsupplydiff) is applied to the series of two or more of the field-effect transistors (FETs).
