臺灣博碩士論文加值系統

數位電視節目透過高頻載送播放，在無線數位電視頭端系統中，利用調諧器將高頻信號調變至中頻，使影像與聲音信號能接收下來。類比電視系統採用單轉換中頻輸出，市售產品大多為雙轉換中頻輸出，本論文高頻調諧器以正交本地振盪源單轉換中頻輸出之架構，並針對目前台灣數位電視廣播之頻率範圍530∼596 MHz，做優化設計。
本論文實現之高頻調諧器包含主動式電感放大器、雙平衡主動式混波器及改良式多相位濾波器，整體考量之依據以映像信號排除的比率（Image Rejection Rate；IRR）作為評斷，模擬發現主動式電感放大器提供調諧器極佳增益，此外主動式混波器及改良式多相位濾波器則為排除映像信號之元件，高頻調諧器設計以CMOS元件為考量，有效大幅度降低晶片面積，且藉由ADS模擬其IRR可超過40 dBm與30 dBm的增益，顯示該電路有較佳的效能表現。
最後以TSMC 18μm 1P6M製程實現所設計之高頻調諧器晶片。針對目前台灣已開播的數位電視頻道，其使用頻率範圍530∼596 MHz，整體系統功率增益維持32 dBm以上、映像信號排除率為32 dBm，功率消耗136.7 mW，晶片面積為 0.497 mm2，若映像信號排除率以30 dBm為基準，整體頻率範圍可延伸至602 MHz，晶片均採用CMOS主動式元件設計，有效節省矽晶片面積。

In wireless DTV front-end system, a tuner is to demodulate a high frequency to an intermediate frequency for receive the video and audio in each program. In traditional analog TV used the single conversion with IF output for its easy implementation. In recent years, a double conversion with IF output is used to improve the tuner’s performance. In this thesis, we study a single chip tuner with MOS techniques. The chip includes low noise amplifier （LNA）, RF mixing, digital voltage control oscillator, and polyphase filter. The LNA is designed with an active inductor to reduce the core size and can achieve about 15dBm. The digital voltage control oscillator consists of 5-stage ring oscillator and one 8-bit DAC（Digital to Analog Converter）. We choose a single conversion with IF and Quadrature LO signal by the combination of polyphase filter, and implement by TSMC 0.18μm CMOS process. The frequency band is designed from 530 MHz to 596 MHz for Taiwan DTV channels. The gain of the entire tuner is anout 32 dBm. And the image rejection ratio（IRR）of the tuner is above 30 dBm. The chip had been simulated with ADS tools in success. And the silicon chip is designed with a full custom layout. The chip size and core size is about 0.497 and 0.1095 mm2, respectively. The maximum power dissipation is 136.7 mW when the chip works on the center frequency 566MHz.
