Abstract
A charge pump includes a first node configured to receive a first voltage and a second node coupled to the first node through a first transistor. The second node is configured to output a voltage having a greater voltage magnitude than the first voltage. A first capacitor is coupled to a third node, and a fourth node is configured to receive a first clock signal. The third node is disposed between a drain of the first transistor and the fourth node. A leaky circuit device is coupled in parallel with the first capacitor for draining charges of a first polarity away from the second node.
