Abstract
(EN)
An exemplary embodiment of the invention provides a charge pump stage (100) that comprises a first input node (101) , a second input node (107) , a decoupling capacity (109) having a first terminal (108) and a second terminal (110) . Further, the charge pump stage (100) comprises a pump control circuit having a first contact node (102) and a second contact node (111) , wherein the first input node (101) is coupled to the first contact node (102) . Furthermore, the second input node (107) is coupled to the first terminal (108) of the decoupling capacity (109) , and the second terminal (110) of the decoupling capacity (109) is coupled to the second contact node (111) and further cou led to ound (112) .
