Compared to conventional hardware GPS receivers (GPSR), software GPS receivers are more suitable for research and development. Software GPS receivers can be dynamically programmed in software to reconfigure the characteristics of GPS receiver and new algorithms can easily be integrated without changing the design of the hardware. However, the most important issue for this approach is the computational load. It can be solved by using the high performance state-of-art digital signal processor. The harshness of space environment, such as Total Ionizing Dosage (TID), Single Event Effect (SEE), always cast certain thread to GPS receiver intended for space applications. Common resolution to cope with this thread is the robustness of space grade EEE parts toward those effects along with the protection of circuit design. Nevertheless, the most of the state-of-art EEE parts are not space qualified. In this study, certain Commercial Off The Shelf (COTS) parts such as COTS level RF Front-End (RFFE) and Digital Signal Processor (DSP) along with single event effect (SEE) mitigation circuit design, are considered in the proposed GPSR design for their advantages, such as availability, performance, size, weight and lead time, over regular space qualified ones.

微機電運動感測器仍蘊藏龐大商機，根據市場研究機構The Information Network 預估： 2012 年全球MEMS 應用市場規模將達154 億美元。目前市場上的運動感測器仍以加速度計為主，因其性能符合要求且價格便宜。市場普遍看好的陀螺儀則成長緩慢，主要原因為元件（機械結構、感測電路）製作精度要求較高，導致成本過高、普及不易。由文獻回顧得知，決定微機械陀螺儀性能的三大因素：（1）機械結構缺陷（imperfections）（2）感測電路缺陷（3）在獲得角度過程中，積分所造成的誤差累積。而目前有關陀螺儀性能改善的研究報告中，大多是利用昂貴的後製程（post processing）來改善機械結構缺陷；複雜的線路設計來改善感測電路缺陷，僅有少數文獻利用回授控制技術來補償機械結構的不確定性，尚未發現任何文獻利用回授控制來補償感測電路的缺陷。此外，僅有少數的文獻提出可直接量測角度的陀螺儀控制方法，然而該方法僅適用於「完美」的陀螺儀機械結構與感測電路（系統參數已知）。本計畫主要針對微機電陀螺儀開發一套完整的即時控制系統，將機械結構的非理想現象、感測線路的非理想現象一併估測、補償，並進而控制陀螺儀的動態，直接獲得角度資訊。由於是以控制器設計（軟體）來提升陀螺儀性能，預期可大幅降低陀螺儀製作成本與技術門檻。此一控制器設計已獲初步成果，並於國際研討會中發表。本計劃將持續進行此控制器設計的改善與探討，同時對於此一控制器的實現，設計製作壓電式陀螺儀，規劃一系列的實驗，以三年的時程來逐步驗證具直接角度量測的微機械式陀螺儀的可行性。

隨著近年來可攜式裝置(Mobile devices)的盛行，其續航能力的要求提高，故半導體元件一直存在的漏電流及偏壓電流功率損耗問題也逐漸被重視。相關的研究指出微波微機械切換器(RF MEMS Switches)具有低耗能(low power consumption)、高絕緣性(high isolation )、低耗損(low insertion loss)、線性特性、可批次製造…等優點，因而被視為可有效解決半導體元件漏電流的問題。然而，微波微機械切換器僅具開關(on/off)功能，其應用不若傳統之IC 邏輯閘方便，此限制使得微波微機械切換器在與傳統數位邏輯線路相結合時，增加許多困擾。本計畫提出了全新發明、設計的微機械邏輯閘，此元件結合微機械切換器的優點與IC 邏輯閘的功能。其目的在於當微機械邏輯閘與傳統數位邏輯線路相結合時，能不需更改原來的邏輯線路，直接與傳統IC 邏輯閘相替換，並降低線路系統的漏電流。微波微機械切換器，因具降低漏電流的優點，已儼然成為微機電研發的明日之星。因此，我們預期此微機械邏輯閘將比目前的微波微機械切換器更容易且廣泛的被使用。本計畫目前的研發進度包括：(1)完成微機械邏輯閘的設計雛型，並以軟體模擬驗證其可行性。(2) 通過交通大學審核，國內、外專利委由律師申請中。(3)完成微機電製作的先期製程(pilot run)及後續製程的修正。未來進度包括：(1)完成微機械邏輯閘製作。(2)元件功能、特性的量測。(3)微機械邏輯閘製程與 IC 半導體製程整合。

由於生物與醫學的產業應用不斷增加，預估2015 年生物感測晶片產值將高達 1000~1500 億日圓。在各式的生物感測晶片設計中，利用微懸臂樑吸附特定物質後造成懸臂樑共振頻率改變，藉由共振頻率的量測來推估生化物質的濃度是主要作法之一。本計劃預計使用TSMC 2P4M 製程來設計製作生物感測晶片，晶片內部包含一電熱驅動、壓阻感測的懸臂樑微振盪器（MEMS 元件），以及一個類比的鎖相迴路（IC 電路）。所設計的微振盪器與鎖相迴路採「回授控制」的方式結合，即將微振盪器視為受控體，鎖相迴路視為回授控制器，藉由鎖相迴路內部參數的設定，使微振盪器自動操作於共振頻率，進而獲得待測物質的濃度。採用此特殊的MEMS 元件與IC 電路的整合方式，其目的在於簡化IC 感測電路設計，進一步實現一不需外部儀器支援的生物感測單一晶片，提高晶片量測精度並降低製作成本。缺點是參數設計不當可能導致系統不穩定。在先前的研究中，本實驗室成功的利用TSMC 2P4M 製程製作出一微振盪器，並實驗驗證其可行性。惟先前研究尚未針對懸臂樑結構進行最佳化設計，且未整合感測電路，因此量測精度受限（5.6 pico-gram/Hz）。此外，該振盪器具有feedtrhough、三階系統、輸入／輸出兩倍頻、等非理想性，使得該設計無法直接與鎖相迴路結合。因此本計畫的工作重點在於：（1）最佳化微振盪器的設計；（2）修正訊號處理流程；（3）以回授控制方式來結合鎖相迴路，完成此一生物感測晶片的設計與製作。

在搖桿內放置慣性感測器是一種實現6 軸定位裝置的可行方法。微機電技術製造之慣性感測器，因其同時具有微型化、製作成本低廉、性能符合要求… 等優點，因而可適用於此一計畫。一般來說，慣性感測器可利用兩種方式來得到六軸定位的資訊。第一個方式是利用三個陀螺儀和三個線性加速規。另一個方式是在一個立方體的不同位置上，貼上六個或六個以上的加速規，並且根據不同位置的加速規的輸出，來計算角加速度與線性加速度。由於在第二個方式中，必須要比第一個方式多一個積分運算才能得到相同的位置與轉動角度。因此當這些量測訊號中有雜訊存在時，積分運算會造成嚴重的Drifting 問題。在這個計畫裡，我們將在遊戲機的定位搖桿上，加裝新式的六軸定位感測器，而此一感測器將兼具上述兩種傳統方式的優點。易言之，我們將設計製作一個具有六軸定位功能之慣性感測單元，而此一量測單元全由加速度規所構成。再者，所有的加速度規都安裝在同一個平面上。根據我們初步的研究結果顯示，我們可以將加速度規置於同一平面上，以讀取角加速度與加速度訊號。目前還有二個問題需要更深入的研究與克服。 (1) 如何減少此一新式六軸定位感測器的積分運算的次數使漂移問題的影響降至最低。 (2)如何用最小的尺寸而達到所需要的解析度。
