针对无线胶囊内窥镜低功耗设计的要求，研究降低胶囊系统中晶振电路能耗的方法。分别采用有源晶振和无源晶振的设计方案进行实验，对比结果证明了两种方案在成像方面的可行性及无源晶振系统在低能耗方面的优越性。实验结果表明，正常工作时无源晶振相比有源晶振系统能耗减少18．4％，胶囊工作时间延长至90min以上。最后制作无源系统的印刷电路板（ PCB）并进行组装，实验表明，该设计方案可以有效降低系统能耗，是合理和可行的。
針對無線膠囊內窺鏡低功耗設計的要求，研究降低膠囊繫統中晶振電路能耗的方法。分彆採用有源晶振和無源晶振的設計方案進行實驗，對比結果證明瞭兩種方案在成像方麵的可行性及無源晶振繫統在低能耗方麵的優越性。實驗結果錶明，正常工作時無源晶振相比有源晶振繫統能耗減少18．4％，膠囊工作時間延長至90min以上。最後製作無源繫統的印刷電路闆（ PCB）併進行組裝，實驗錶明，該設計方案可以有效降低繫統能耗，是閤理和可行的。

Aiming at the requirement of low power consumption in the design of capsule endoscopy ,means of decreasing the power consumption of crystal oscillator circuit are studyed .Contrast experiments are designed for the alternative crystal and oscillator scheme,and it has been proved by experiment of the imaging practicability of the two schemes and superiority of the crystal one in consumption .Experimental results indicate that the crystal scheme would reduce power consumption of the system by about 18.4%and working time of the capsule is prolonged to more than 90 minutes.PCB boards are then made and the components are assembled using crystal oscillator .Experiments show that the design is reasonable and feasible for effectively reducing the system ’ s power consumption .
