Abstract:
    A charge pump circuit and method thereof are provided. The example charge pump may include a first switch transistor supplying a first current to an output node in response to a first signal to increase a level of current at the output node, a second switch transistor sinking a second current from the output node in response to a second signal to decrease a level of current at the output node and a controller reducing an amount of the first and second currents if the first and second currents are generated concurrently. The example method may include supplying a first current to an output node in response to a first signal to increase a level of current at the output node, sinking a second current from the output node in response to a second signal to decrease a level of current at the output node and reducing an amount of the first and second currents if the first and second currents are generated concurrently.
