電荷漏泄
英文
charge leakage-
The carrier wave is modulated directly by the baseband signal at several frequency point in l band and s band. firstly, this paper clarifies the theory of i / q modulation, elaborates evm and acpl, and analyzes the effect of amplitude and phase unbalance and dc offset on evm. secondly we review the basic principle of phase locked loop and it ’ s composing parts, including the basic conception and design method of pll frequency synthesizer, especially introduce the charge pump pll frequency synthesizer in detail
首先，在闡述i / q正交調制基本原理的基礎上，通過對誤差矢量和鄰近通道功率泄漏的詳細分析，定性、定量地討論了各種非理想電路因素（如相位不平衡、幅度不平衡、直流偏差等）對調制器性能的影響;其次，介紹了鎖相環的工作原理和基本組成部分，包括鎖相環的設計和環路濾波器的設計，特別詳述了電荷泵鎖相頻率源;第三，介紹了採用直接調制技術模擬衛星信號的射頻前端的設計;最後，對整個直接射頻調制系統進行測試，結果基本上達到了課題要求。Finally, after the long - term ion migration test, we analyzed the relation between the current and accumulative charge with the test time, computed the ion mobility and migration distance, and analyzed the distribution variety of na + and k + in the test samples
對10支試品進行了長期離子遷移試驗，測量了泄漏電流曲線和累計電荷量隨時間變化曲線，計算了試品的離子遷移率和遷移距離，並對試品na ~ + 、 k ~ +的含量進行了化學分析。Due to the charge sharing and charge leakage phenomena in the traditional charge - pump, a new charge - pump with current control technique is designed in this thesis. in the circuit design, a simple positive feedback is employed to expedite the switching speed. the simulation results show that the charge sharing and charge leakage phenomena can be effectively prohibited in the proposed charge - pump
2 .針對傳統電荷泵中存在電荷泄漏和電荷共享現象，設計出了一種採用電流控制技術的新型電荷泵，電路中巧妙地運用了一個簡單的正反饋，以加快開關速度，模擬結果表明，所設計的電荷泵能有效的抑制了電荷泄漏和電荷共享現象。Charge pattern leakage
