摘要


本晶片為採用重複使用延遲線的頻率合成器,此晶片採用 TSMC 90 奈米製 程,下線面積約為 1mm x 1mm,核心電路面積約為 0.18mm x 0.25mm。在電源供 應 1V 下,延遲鎖定迴路的輸出為 800MHz,參考突波為-30.2dBc,功耗為 12.2 mW。(功耗包含輸出級)

並列摘要


This chip is a frequency synthesizer that uses a reusable delay line. This chip uses TSMC 90nm process. The total area is about 1mm x 1mm, and core area is 0.18mm x 0.25mm. When the power supply is 1V, the maximum output of the delay locked loop is 800 MHz, and the reference spur is -30.2 dBc, power consumption is 12.2 mW.(Power including output buffer)
