In this paper, a design methodology for an efficient programmable delay line using reduced hardware resources is presented. The proposed methodology is scalable and reuses the given buffer elements multiple times to accomplish the task. A substantial absolute delay required in the system is achieved with an equivalent circuit using limited number of buffers. The novel design of the delay line is compared with the conventional architecture in terms of area, leakage power and process variability. It is demonstrated that the proposed design is better than its predecessors in all dimensions.
