【摘要】：近幾年來(lái)，隨著無(wú)線通信系統(tǒng)的不斷發(fā)展和工藝制造水平的飛速進(jìn)步，基于無(wú)線通信技術(shù)實(shí)現(xiàn)的一系列應(yīng)用（例如蜂窩電話、藍(lán)牙、WiFi、GPS等）在人們的日常生活中扮演著越來(lái)越重要的角色，硅基半導(dǎo)體工藝尤其是CMOS工藝因其具有易集成、低成本、低功耗、高性能等特點(diǎn)符合目前無(wú)線通信發(fā)展的趨勢(shì)，得到了廣泛的應(yīng)用。移相器是相控陣系統(tǒng)、Serdes以及一些基于相位調(diào)制的收發(fā)機(jī)中極為重要的模塊，單刀雙擲開(kāi)關(guān)在非全雙工收發(fā)機(jī)中是必不可少的部分。目前，人們對(duì)于無(wú)線通信系統(tǒng)不斷提出新的要求，因此設(shè)計(jì)尺寸小、性能優(yōu)、可靠性好的移相器及開(kāi)關(guān)具有很強(qiáng)的實(shí)踐價(jià)值與意義。 本課題提出了5-bit無(wú)源移相器及非對(duì)稱單刀雙擲開(kāi)關(guān)。對(duì)于移相器從微波原理通過(guò)公式推導(dǎo)電路原理及各性能指標(biāo)，用定性與定量?jī)煞N方法分析如何提高性能。對(duì)于開(kāi)關(guān)了解電路原理、用途，理論分析每一項(xiàng)指標(biāo)由哪些因素決定，對(duì)比不同結(jié)構(gòu)的利弊。之后用仿真驗(yàn)證推導(dǎo)結(jié)果，完成電路圖和版圖設(shè)計(jì)，最終完成流片和對(duì)芯片的測(cè)試工作。 本文系統(tǒng)論述了基于CMOS工藝的無(wú)源移相器和單刀雙擲開(kāi)關(guān)的理論與實(shí)現(xiàn)，，并深入淺出的研究和討論了設(shè)計(jì)過(guò)程中的許多關(guān)鍵技術(shù)。 本文基于TSMC90nm CMOS工藝，針對(duì)系統(tǒng)整體要求，選擇移相精度為5-bit，沒(méi)有功耗的無(wú)源反射型結(jié)構(gòu)；非對(duì)稱結(jié)構(gòu)單刀雙擲開(kāi)關(guān)作為移相器和開(kāi)關(guān)最終的設(shè)計(jì)方案。詳細(xì)介紹了兩個(gè)課題中用到的無(wú)源器件理論分析、設(shè)計(jì)過(guò)程及仿真驗(yàn)證。本次設(shè)計(jì)中電路及版圖的設(shè)計(jì)與仿真使用Cadence公司的Virtuoso工具中的Schematic/LayoutEditor和Analog Design Environment。無(wú)源器件的仿真使用Ansoft HFSS及Sonnet。
[Abstract]:In recent years, with the continuous development of wireless communication system and the rapid progress of process manufacturing, a series of applications (such as cellular telephone) based on wireless communication technology have been implemented. Bluetooth WiFi GPS) plays a more and more important role in people's daily life. Silicon based semiconductor process, especially CMOS process, has the characteristics of easy integration, low cost, low power consumption, high performance and so on. Phase shifter is a very important module in phased array system and some transceivers based on phase modulation. Single pole double throw switch is an essential part of non-full-duplex transceiver. New requirements have been put forward for wireless communication systems, so the design of phase shifters and switches with small size, excellent performance and good reliability has strong practical value and significance. In this paper, a 5-bit passive phase shifter and an asymmetric single-pole double-throw switch are proposed. Qualitative and quantitative methods are used to analyze how to improve performance. For the switch to understand the circuit principle, use, theoretical analysis of each index is determined by what factors, compare the advantages and disadvantages of different structures. Complete circuit diagram and layout design, the final completion of the chip and chip testing work. In this paper, the theory and implementation of passive phase shifter and single pole double throw switch based on CMOS technology are systematically discussed, and many key technologies in the design process are discussed. In this paper, based on TSMC90nm CMOS technology, a passive reflection structure with phase shift accuracy of 5-bit and no power consumption is selected according to the overall requirements of the system. Asymmetric single-pole double-throw switch is the final design scheme of phase shifter and switch. The theoretical analysis of passive devices used in the two topics is introduced in detail. The circuit and layout of this design are designed and simulated using Schematic/LayoutEditor and Analog Design Environment in Virtuoso tools of Cadence Company, and Ansoft HFSS and Sonnet are used in the simulation of passive devices.
