本論文主要目的為利用所提出的緩和彎角架構先行降低差動對彎角處本身的不平衡性,再經由於緩和處同時應用電容及電感補償達到混合式補償以強化共模雜訊抑制效果。
為了有更全面的結果分析,將設計目標訂為:以緩和彎角混合式補償改善混模參數中模轉換(Scd21)的同時;也能保有差模訊號的完整性,即差模損耗(Sdd21)不至於因為加入補償電路受到太大的影響。
時域的分析除了統整補償前後的共模雜訊與其眼高及眼寬,也同時比較補償後150度緩和彎角與未補償90度直角架構之共模雜訊改善百分比例,可達59.3 %,並歸納出符合設計目標且抑制效果最佳的混合式補償。
模擬與量測部分的驗證頻率範圍從DC至6GHz,在此範圍內,最佳抑制效果的模轉換皆優於-17.262 dB,差模損耗皆低於2.798 dB,量測結果與模擬結果有很高的一致性。此外,也利用模擬的方式來驗證集總元件等效電路的正確性。
Proposed smooth bends structure is used to reduce the area of unbalance differential bend in order to enhance suppression of mode conversion and common-mode noise. At the same time, the proposed structure keeps differential-mode transmission level to maintain the integrity of differential signal. Moreover, the proposed hybrid compensation method is also used on smooth bends structure, and concludes that smooth bends structure with the “LCL” compensation way has the best performance of all. For the mode-conversion, it can be suppressed under -17.262 dB, and the insertion loss remains all below 2.798 dB from DC to 6 GHz. The significant advantage of proposed structure is that it can be fabricated on PCB easily to lower the cost. In time domain analysis, the common-mode noise can be reduced by 59.3 % compared with right-angle bend structure. Measurements on proposed structures have good agreement with simulations. All things considered, the proposed smooth bends structure successfully reduce the effect of unbalance for better mode-conversion suppression and the best hybrid compensation way is concluded.
