Apparatus for interpolating between a first signal edge and a second signal edge, a method for controlling such apparatus, and an interpolation cell for a digital-to-time converter

摘要

An apparatus for interpolating between a first signal edge and a second signal edge is provided. The apparatus includes a plurality of interpolation cells coupled to a common node. At least one of the plurality of interpolation cells is configured to supply, based on a control word, the first signal edge and/or the second signal edge to the common node. Further, the apparatus includes a control circuit configured to activate all of the plurality interpolation cells in a first mode of operation, and to deactivate part of the plurality of interpolation cells in a second mode of operation.
