Abstract: Aspects of the disclosure are directed to adaptively delaying an input signal. In accordance with one aspect, an apparatus includes a plurality of delay units, wherein each of the plurality of delay units includes a substantially similar output load characteristic; a plurality of buffer units, wherein each of the plurality of buffer units is coupled to one of the plurality of delay units; wherein a quantity of the plurality of delay units equals a quantity of the plurality of buffer units; an additional delay unit coupled to a delay unit output of one of the plurality of delay units; and a one-hot decoder coupled to each of the plurality of buffer units, the one-hot decoder configured to enable one and only one of the plurality of buffer units.
