为了改善振荡器的输出波形在RC正弦波振荡器中需要采取什么措？

本设计是应用电路仿真软件EWB MULTISIM 8 设计仿真数字数字锁相频率合成。目的是以一个具有高度稳定性的晶体振荡器为参考频率在一个较宽的频带内合成多个频率点，从而使每个频率点都具有晶体振荡器频率标准的稳定性。设计中采用的形式是数字和模拟相结合的形式，波形为方波和正弦波，采用的方法是锁相环技术（PLL）。整个过程需要经历参考信号的起振，压控振荡器的起振，相位锁定跟踪三个过程。最终实现的结果是以参考信号为100KHz的晶体振荡器合成两个分别是10MHz和11MHz的信号方波。

  The design is the application of circuit simulation software design and simulation of figure 8 EWB MULTISIM PLL frequency synthesizer。
  The purpose is to have a high stability reference crystal oscillator frequency synthesis in a number of wide band frequency,so that every point is the frequency of the crystal oscillator frequency stability standards。
  Design the form of a combination of digital and analog form for the square and sinusoidal waveform。
  PLL technology is a method (PLL)。The whole process requires the reference oscillator signal, the oscillator VCO, three phase locked tracking process。
  The result was the ultimate realization of the crystal oscillator reference signal to 100KHz and 11MHz, 10MHz is the synthesis of two square wave signal。
