Title:
CHARGE PUMP APPARATUS AND METHOD FOR GENERATING OUTPUT POWER
Document Type and Number:
Japanese Patent JP2010119292
Kind Code:
A
Abstract:
To provide a method and an apparatus for a charge pump having various features.
Noise injection from a charge pump to other circuits may be reduced by limiting both positive and negative clock transition rates and limiting drive currents within clock generator driver circuits or by increasing a control node AC impedance of certain transfer capacitor coupling switches. A single-phase clock may be used to control all active switches within a charge pump, and capacitive coupling may simplify biasing and timing for clock signals controlling transfer capacitor coupling switches. Any combination of such features of the method or apparatus may be employed to make the charge pump design simple and easy for a wide range of charge pump architectures.
