    摘要: A clock interpolation circuit for setting and controlling a phase of an output clock that is derived from an interpolation of multiple input clocks. Interpolation is performed by capacitively weighting the multiple clocks. A select and control circuit provides the ability to select different capacitance values to control the weighting. An optional buffer stage is also provided to sharpen the edge transitions of the interpolated clock.
