ABSTRACT:
A device for providing a constant output voltage based on a variable input voltage is provided. The device may include: (1) a charge-pump comprising a plurality of cells, wherein each of the plurality of cells can be configured as an input cell, a stepping cell, or a load cell; (2) a comparator; and (3) a differentiator coupled to the comparator output, wherein the differentiator is configured to monitor the comparator output and produce a reset pulse each time the comparator output changes its state. The device may further include: (1) a decimator; (2) an up/down counter; and (3) a controller for detecting whether the device is operating in a first predetermined mode or a second predetermined mode, wherein the two modes relate to the configuration of the plurality of cells into the input cell, the stepping cell, and/or the load cell.
