一种频率稳定的改进型CMOS环形振荡器

An Improved CMOS Loop Oscillator with Stable Frequency

在传统的环形振荡器基础上,提出了一种改进的CMOS环形振荡器。它克服了传统CMOS环形振荡器振荡频率随电源电压变化而严重不稳的缺点。通过仿真,得到了电源电压与振荡频率的对应关系。

An improved CMOS loop oscillator is proposed in the paper, which overcomes the shortcomings of the traditional CMOS loop oscillator, whose oscillating frequency varies a lot with power supply voltage, and generates stabler frequency than the traditional loop oscillator The relation between the power supply voltage and the frequency is obtained from simulation
