【正文】 片，它可以是正方形、矩形或圓形等），在它的兩個對應面上涂敷銀層作為電極，在每個電極上各焊一根引線接到管腳 上，再加上封裝外殼就構成了石英晶體振蕩器，簡稱為石英晶體或晶體、振蕩。根據(jù)仿真后的電路原理圖進行實物的連接和調(diào)試，從而完成整個正弦波振蕩器的設計。實驗儀器設備： 數(shù)字存儲示波器 1臺 無感起子 1把 數(shù)字萬用表 1臺 12V直流穩(wěn)壓電源 1臺本次設計首先以NPN型晶體管2N2222和10M石英晶體為基礎設計出并聯(lián)型振蕩器，通過對各種不同形式的并聯(lián)型振蕩器做出比較之后，綜合設計出一個通過開關可實現(xiàn)并聯(lián)轉(zhuǎn)換的石英晶體正弦波振蕩器。 Series parallel。關鍵詞：晶體；振蕩器；并聯(lián)；Multisim仿真ABSTRACT Quartz crystal oscillator is a kind of high precision and high stability of the oscillator, which has been widely used in color TV puter remote control and other kinds of oscillation circuit, and munication system used for frequency generator quartz resonator for high frequency stability, it is mainly used in request frequency is very stable oscillation circuit of resonance element but quartz crystal cost is higher, so in less demanding circuit usually use ceramic resonance design using quartz crystal piezoelectric effect, made of crystal oscillator method to do a more indepth study on the oscillator principle and quartz crystal oscillator principle are described in detail and through the Multisim software design simulation the parallel type quartz crystal oscillator, according to the parallel resonance type crystal oscillator principle using carat splash circuit draw the schematic diagram of the parameters, the calculation and real production debugging in physical and simulation debugging, and successfully appear waveform, proved the reliability of the above theory, and ply with the design requirements is a successful course design. Key words Crystal。對實物和仿真進行調(diào)試，并成功出現(xiàn)波形，證明了上述理論的可靠性，且符合設計要求。但石英晶體成本較高，故在要求不太高的電路中一般采用陶瓷諧振元件。通信電子線路課程設計說明書 晶體正弦波振蕩 院 、
