正弦波压控振荡专业课程设计样本

正弦波压控振荡专业课程设计摘要随着现代通信技术的进展，各种通信设备层出不穷，涉及信息收发的各种仪器在调制和解调过程中，都必须依靠高精度的振荡源，否则信息将无法发送和接收，因而个正通信设备中几乎都离不开高稳定度的振荡源。振荡器的种类有很多，包括反馈式振荡器、负阻式振荡器等，本次课程设计主要完成正弦波压控振荡器（VCO）的设计。包含有压控元件作为频率控制器件的振荡器就称为压控振荡器，压控振荡器广泛应用于各种发射机载波源、扩频通讯载波源或作为混频器本振源。本次设计利用晶体管、变容二极管等分立元件完成相关设计，并达到设计要求。关键字：正弦波 振荡器 变容二极管 VCOAbstractWith the development of modern communications technology, a variety of communications equipment and related information sent to or from a variety of instruments in the modulation and demodulation process, must rely on high-precision oscillations, otherwise the information will not be able to send and receive, and thus a positive communication equipment almost without high stability of oscillations. Oscillator types include feedback oscillator, negative resistance oscillator, etc, this course is designed mainly to complete the sine wave voltage controlled oscillator (VCO) design. Contains a voltage-controlled components as the oscillator frequency control device is called a voltage controlled oscillators, voltage controlled oscillators widely transmitters carrier source, spread spectrum communications carrier source or as a mixer local oscillator. This design using transistors, varactor diodes, etc to complete discrete components, and related design meet the design requirements.Keywords: sine wave oscillator varactor VCO1 正弦波压控震荡器介绍正弦波振荡器的作用是产生频率稳定、幅度不变的正弦波输出。广泛应用于各种电子设备中，特别是在通信系统中起着重要作用，它是无线电发送设备的心脏部分，也是超外差式接收机的主要部分。根据选频网络所采纳的器件可以分为 LC 振荡器、RC 振荡器、晶...
