摘要： An apparatus is described which includes a delay-line with reasonably matched delay cells and some logic to ascertain both a correct number of DC-DC converters and interleaving angles or phase offsets. The apparatus measures an operating frequency in real-time in multiples of the individual delay cells of the delay-line. The smaller the period, the higher the load coupled to the DC-DC converters and, therefore the greater the number of DC-DC converters are needed to service the load. The period determines the load and can be used to determine the number of DC-DC converters needed and thereby accomplishing autonomous phase enabling/shedding.
