Abstract
An increased internal operating voltage for an integrated circuit can be generated with two two-stage charge pumps, ensuring reliable operation even in the event of an external voltage supply Vext=1.8 V or less. The two charge pumps cooperate with a common first stage in a cyclic sequence. A temporally offset organization of the cycles of the two charge pumps enables operation in a manner that is free from disturbances. Moreover, the large chip area required for capacitors can advantageously be considerably reduced.
