摘要：

传统施密特型压控振荡器存在输入电压下限值较高、最高振荡频率较低等缺点。针对这两个问题,文中介绍了一种具有新型充放电电路结构的施密特型压控振荡器,并在0.18 μm工艺下对电路进行了仿真。结果表明,相对于传统施密特型压控振荡器,新型振荡器输入电压下限值有所下降,且最高振荡频率也有明显提升。

关键词: 输入电压, 振荡频率, 压控振荡器

Abstract:

Traditional Schmitt trigger type VCO has two main problems:the minimum value of input voltage is too high and the maximum value of oscillating frequency is too low.To solve these two problems,this article introduces a Schmitt trigger type VCO with new structure of charging and discharging circuits,and simulates it with the implementation of the 0.18 μm technology.The result shows that the minimum value of input voltage of new VCO has decreased considerably while the maximum value of oscillating frequency has boosted obviously compared with the traditional Schmitt type VCO.

Key words: input voltage;oscillating frequency;VCO
