发明名称 Low ripple bias voltage generator
摘要 A charge pump essentially incorporating parallel connections of low capacity charge pumps, where each low capacity charge pump is controlled by a clock signal, where the clock signal associated with a low capacity charge pump has a phase different than the other clock signals. Hence, the output of these essentially parallel connected charge pumps will have a ripple period which is a fraction of the period of any single clock signal, wherein the fraction is equal to 1/n, where n is the number of parallel low capacity charge pumps. This results in a ripple magnitude of 1/n that of charge pumps using a single clock source with identical input and output capacitance.
