Abstract
A voltage generator may include a plurality of charge pumps, plural sets of delay pipelines and a phase controller. Given M delay pipelines having N stages each, there may be M*N charge pumps each having a triggering input coupled to a respective stage or a respective pipeline. The phase controller may include a plurality of phase control stages interconnecting among the delay pipelines to induce timing offsets among the outputs of the delay stage. In an alternate design, intermediate nodes among the pipeline's delay stages may be coupled to triggering inputs of a sub-set of the charge pumps. The phase controller may have a plurality of phase control stages coupled, respectively, between the intermediate nodes of the delay pipeline and intermediate nodes of the phase control stages may be coupled to triggering inputs of another sub-set of the charge pumps.
