  相較於脈波雷達系統,連續波雷達系統更適用在很多方面的應用,尤其是在小型的、輕量的雷達偵測器的要求。調頻連續波雷達使用低截擊概率的調變波形,也很適合製造很好使用的簡易式固態傳輸器。
  隨著半導體製程技術的演進,射頻電路和數位電路有可能可以整合製作成一顆系統晶片,類比數位轉換器即是這兩種電路之間的「翻譯員」。於是,在計畫中是設計一個快閃式類比數位轉換器,並且先導計畫是設計一些測試鍵來下線製作。本文的測試鍵是使用TSMC 0.18μm製程技術來製作,並且模擬八位元快閃式類比數位轉換器的電路性能。還有,此文提出線性主動負載的設計方法。
  測試鍵的功能性量測結果,驗證了電路模擬的結果,快閃式類比數位轉換器的核心電路:串聯式主動電阻分壓器、比較器和Second Latch皆能正常運作。
  在本文中,我們介紹一種數位式比較器,它可以減小佈局面積和降低功率消耗,並且有較大的輸入電壓範圍。它的電路架構和時間模式比較器不同,特性也不相同,所以它的輸入電壓範圍大於時間模式比較器。
The Continuous Wave Radar system is more suitable than the Pulse Radar system for many applications, especially in situations where a small, lightweight Radar sensor is required. The FMCW Radar system uses a very low probability of intercept waveform, which is also well suited to make good use of simple solid-state transmitters.
To meet the technique of CMOS processing trend, it is possible to combine a radio frequency circuit with a digital circuit and could be made on a chip of SOC (System on a Chip). The ADC (Analog to Digital Converter) is a “translator” between these two kinds of circuits. Thus, a proposal orders to design a Flash ADC and guides it to make some circuits of test key by tape out. The TSMC 0.18μm processing is be used here to realize and we simulated the circuit performance of 8-bit Flash ADC. Furthermore, this dissertation proposes a design methodology for the Linear Active Load.
Functional measurement results of test keys have confirmed circuit simulation result. Kernel circuits of a Flash ADC are working normally, and they are Cascaded Active resistive voltage divider, comparator and level shifter.
In this dissertation, we propose to a kind of digital comparator that it can reduce layout area, diminish power consumption and it has larger input voltage range. Its architecture is different from Time-Mode Comparator, and the characteristic is different, too. Therefore, its input voltage range is larger than Time-Mode Comparator.
