Abstract:
A charge-pump circuit for charge-share suppression. A first switching element is coupled between a first connecting node and an output terminal. A first load receives a current from a first current source and outputs an output voltage at the output terminal when the first switching element is in “On” state. A status of a second switching element is controlled by the input signal and opposite to the status of the first switching elements A second current source is coupled to the second switching element through a second connecting node. A second load receives the output voltage when the second switching element is in “On” state. A first feedback circuit maintains a constant relation between the output voltage and a voltage of the first node. A second feedback circuit maintains a constant relation between the output voltage and a voltage of the second node.
