研究期間：10108~10207;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.
