Low noise charge pump method and apparatus

摘要: A charge pump method and apparatus is described having various aspects. Noise injection from a to other circuits may be reduced by limiting both positive negative clock transition rates, as well drive currents within generator driver circuits, also increasing control node AC impedance of certain transfer capacitor coupling switches. single-phase used many all active switches pump, capacitive simplify biasing timing for signals controlling Any combination such aspects the or employed quiet and/or designs over wide range architectures.
