為能實現射頻前端系統之最佳化設計,本研究將發展「系統元件化」的微波電路設計技術,藉由將射頻前端子系統乃至系統功能整合於微小化之單一電路元件,且各功能無法於此元件之電路架構中明確劃分開來,從而能超越製程極限進一步大幅減小電路面積,並藉此降低傳統射頻前端系統設計中元件間的不匹配損耗與功能重複之問題,從而提昇效能,並有助於單一晶片系統與單一系統封裝的實現。本三年計畫擬針對射頻前端系統中不涉及頻率轉換的主、被動電路功能方塊,實現成新式單一元件,而非僅是實現於同一製程。而此一「系統元件化」設計概念,不同於傳統針對各電路方塊各自獨立尋求最佳化設計之進行方式,亦不尋求一通用之解決方案,而是從系統應用角度出發,以由上而下的方式,根據給定系統規格,尋求射頻前端系統最佳實施方式的特解,從而達成系統整體功能不變之下的最佳化設計。In this study, in order to pursue the optimal design of RF frontend, the “componentized system design” approach is proposed. It is achieved through integrating the functional blocks of a RF sub-system or even system into one single component that exhibits minimal circuit size, and each function integrates by this component can not be separated explicitly from its circuit architecture. In this way, one may get beyond the process limit and reduce the circuit area effectively. In addition, the problems in conventional RF frontend design such as mismatch losses and redundant functions between neighboring functional blocks can be minimized. This will then improve the overall system performance and will be very helpful for the realization of RF system-on-chip and system-on-package. This three-year project focuses on the integration of all RF function blocks involving no frequency conversion into one single component, and it does not mean just implementing those function blocks in the same process technology. The proposed “componentized system design” approach is different from the conventional way of RF frondend design, which focuses on the optimization of individual circuit elements and expects good results when integrating them all together. Also, it is not aimed at finding a general solution to optimal RF system design. In contrast, the proposed “componentized system design” starts from the system point-of-view, and uses a top-down approach to seek for the special solution to realize a specific system with certain functions so as to achieve optimal performance. 研究期間:10008 ~ 10107
