Abstract:	在改進的Colpitts配置的平衡SAW振盪器進行了研究。，以提高啟動的交叉耦合對嵌入。由於絕緣功能的聲表面波諧振器，鎖存器的問題可能發生。一個精心設計的主放大器和交叉耦合對CMOS晶體管之間的縱橫比，解決了這個問題。借助於固有的交叉耦合的極性相反的對SAW諧振器的端子上出現，星級生長最快的速度相比，公知的Colpitts振盪器。過渡時期大幅縮水。完整性3種單端，平衡的Colpitts振盪器，和交叉耦合的比較在相同的幅度在整個諧振器的品質因數（FOM），圖。還示出的功率消耗和相位噪聲。 The balanced SAW oscillator in the modified Colpitts configuration is studied. To enhance the start up a cross-coupled pair is embedded. Owing to the insulating feature of SAW resonator, the problem of latch may happen. With a careful design in the aspect
