It is widely used in many circuits, such as high precise comparators, a / d and d / a converters, drams, flash memory circuits, and other analog or mixed circuits. therefore, it is significant to develop a voltage reference circuitry that is compatible with digital cmos technology and can be integrated into a system on a chip ( soc )
基準電壓源（ voltagereference ）是超大規模集成電路和系統的重要組成部分，應用於高精度比較器、 a d和d a轉換器、隨機動態存取存儲器、閃存電路等多種電路和電路單元，亦為系統集成晶元（ soc ， systemonachip ）所廣泛採用。 -
Key technologies are first introduced here such as the phased array antenna theory, dbf ( digital beam forming ) theory and the configuration of transmit and receive ( t / r ) modules. then part of analog circuitry is optimized with the digital technology. cell circular microstrip disk antenna successfully developed based on the theory of microstrip antenna, the four - celled circular microstrip disk antenna arrays are designed, simulated and analyzed with eda tools - hfss, opt1metrics
本文以相控陣雷達組成為主軸，逐一對相控陣雷達關鍵技術中的天線陣原理、數字波束形成（ dbf ）技術和收發（ t r ）組件組成進行詳細的分析，利用數字技術對傳統相控陣雷達設計方案中的模擬電路部分進行改進；在理論設計單元圓形微帶貼片天線單元的基礎上，利用微波模擬軟體hfss和optimetrics對四單元的圓形微帶貼片天線陣進行設計與模擬；對相控陣雷達的幅相監測技術進行理論分析和討論，選擇最佳的幅相監測方案。 -
A switch ic for analog signal processing is designed and implemented, which can fulfill the functions of sampling, weighting, controlling and summing of high frequency analog signals. the circuit consists of three parts : four channel analog switches, a voltage reference and the control circuitry. each analog switch is comprised of two high - transconductance n - mosfets with high w / l ratio, which realize the fine tuning and coarse tuning of the input signal respectively
本文研究並設計了一種可對高頻信號進行取樣、加權、控制、疊加的模擬信號處理丌關集成電路，它包括模擬開關、電壓基準源和移位寄存器三個功能模塊，通過兩個高寬長比的高跨導nmos晶體管實現權值的粗調和微調。 -
Present technology offers no cure for this problem, which also limits the performance possible from broadband monolithic mixed signal ics having analog and digital circuitry on a single chip
目前的工藝尚無法解決這個問題，同時這個問題也制約著寬帶單片混合信號電路（在一個晶元上同時存在數字電路和模擬電路）的技術進步。
