Abstract

本計劃目的在研究使用異質整合技術，應用於多模多頻段無線通訊系統，達到0.9~10GHz寬頻可重組式性能目標。為達到此頻寬，內容將利用MEMS元件優越特性提升設頻電路效能。架構上應用六埠接收機架構突破傳統正交訊號解調架構的問題。在本計劃中，關鍵電路例如可重組式低雜訊放大器將會討論及設計。配合六埠架構，實現完整系統，並利用已開發的微機電設計平台驗證設計流程。因此在射頻電路設計可以大幅降低複雜度，簡化難度，降低功率消耗，及降低成本。This project is targeting to develop heterogeneous integrated technology for 0.9~10GHz broadband reconfigurable receiver front-end applied to multi-standard communications. To accommodate for the broad bandwidth, MEMS technology shall be addressed, incorporated into the standard CMOS technology to pursue for better system performance. As such, the six-port receiver architecture will be adopted to avoid those common issues exhibited in the traditional I/Q demodulators. Key circuit blocks include reconfigurable low-noise amplifiers (LNA) shall be carefully studied for the broadband concern. The six-port receiver will be realized and verified by developed MEMS design platform. The design complexity thus will be greatly reduced to achieve low cost and low power.
