技術摘要 / Our Technology: |
本發明所提出的低功率延遲線電路,是以環狀計數器來作為位址解碼器,並以鎖存器陣列來儲存資料。為了降低功率消耗,本發明以一種樹狀閘式時脈驅動器來驅動環狀計數器,使得作為位址解碼器的環狀計數器的功率消耗大為減低。而在鎖存器陣列的資料儲存部份,本發明也採用樹狀閘式驅動器的做法,來驅動資料的輸入、輸出端。本發明所提出的功率延遲線電路,除了在功率消耗上可達到比SRAM記憶體延遲線更低之外,還具有能在高速下操作、且電路佈局面積和SRAM記憶體延遲線更小等特點。
A low-power delay buffer circuit is provided, which utilizes a ring counter as address decoder and a latch array for memory. To reduce power consumption, a gated-clock driver tree is applied to the ring-counter addressing architecture. Moreover, a similar gated-driver tree is applied to the input and output ports of the latch array. The delay buffer circuit not only could achieve a power consumption lower than SRAM-based delay buffers, but also could operation under high frequencies and take up less layout area than SRAM-based delay buffers.
