Abstract:	本論文發展出兩個使用雙點調變機制的新型的展頻訊號產生器，其同時改變除法器及電壓控制振盪器。雙點調變中的全導通特性可以增加調變頻寬使得調變的準確度及由差異樍分器所產生的時間抖動可以一起改善。此技術導致所提出的展頻訊號產生器具有面積小及功耗低的特點 A new technique utilizing the two-point modulation (TP) for a spread-spectrum clock generator (SSCG) for Serial ATA is presented in which the divider ratio is varied by a ΣΔ modulator, and the voltage-controlled oscillator is modulated.
