Diagonal matrix delay

A method of delaying an input signal, comprising:

• a.) serially receiving the input signal at a plurality of rows of delay elements;
• b.) selecting a row of delay elements from among the plurality of rows of delay elements;
• c.) selecting an output of a delay element in the selected row by supplying a column selection signal to a tap buffer associated with the delay element and to corresponding tap buffers associated with each of the plurality of rows,
• wherein tap buffers selected by a column selection signal are offset between contiguous rows by at least one column to form an oblique arrangement of columns of tap buffers relative to the plurality of rows of delay elements;
• and
• d.) outputting an incrementally-delayed input signal from the selected delay element in the selected row.

A method of selecting a delay of an input signal, comprising:

• a.) selecting a row of delay elements from among a plurality of rows of delay elements;
• b.) selecting an output of a delay element in the selected row by supplying a column selection signal to a tap buffer associated with the delay element and to corresponding tap buffers associated with each of the plurality of rows,
• wherein tap buffers selected by a column selection signal are offset between contiguous rows by at least one column to form an oblique arrangement of columns of tap buffers relative to the plurality of rows of delay elements;
• and
• c.) changing row selection from the selected row to a contiguous row of the plurality of rows in the absence of a change in the selection of the corresponding tap buffers.
