Contrapose to the instability of the third - order charge - pump pll system, the loop optimization method is employed in system level design to decide the bandwidth and phase margin, therefore the loop bandwidth locates at the maximum phase margin to guarantee the stability of the system. according to tsmc 0. 35 m sige bicmos model, the sub - circuits in the designed pll and the whole system are simulated and verified by the cadence spectre
5 .根據tsmc0 . 35 msigebicmos工藝模型,利用cadencespectre模擬軟體對所設計的電荷
泵鎖相環路中各個模塊及整個系統進行了模擬模擬,模擬結果顯示,在1 . 5v電源電壓下,頻率為200mhz的參考輸入信號,輸出中心頻率為800mhz ,分頻電路採用4分頻,環路
帶寬為10mhz ,捕獲時間大約為0 . 92 s ,功耗大約為15mw ,達到了設計指標。

For the long term operation, the growth rate of temperature is higher than that of average temperature of the soil, the system analysis should therefore be implemented from the viewpoint of both energy equilibrium and heat barrier in order to ensure the whole stability and reliability
長期運行中,熱屏障
帶的溫度增長速率要高於土壤平均溫度的增長,建議從負荷平衡和熱屏障兩個角度進行分析,以保證地源熱
泵系統穩定可靠的運行。
