Abstract
Methods and systems of reducing a substrate noise in a charge pump having a flying capacitor are provided. An input node of the flying capacitor is pre-charged at a first slew rate. The input node of the flying capacitor is charged at a second slew rate that is faster than the first slew rate. The input node of the flying capacitor is pre-discharged at a third slew rate. The input node of the flying capacitor is discharged at a fourth slew rate that is faster than the first slew rate.
