The local supply voltage generator for the digital CMOS integrated circuit which possesses the analog signal processing circuit

摘要

The digital CMOS integrated circuit (120), series 2 or the field-effect transistor above that (FET) the analog signal processing circuit which it possesses is had. Those FET have maximum approved supply voltage value (Vmax). The supply voltage which the digital CMOS integrated circuit (120) furthermore, maximum approved supply voltage value (Vmax) is larger and is raised (Vsupplydiff) the local charge pump in order to form (135) it possesses. The local charge pump (135), this in order the supply voltage which is raised (Vsupplydiff) series 2 or the field-effect transistor above that (FET) to be supplied, it is constituted.
