摘要
在对传统的数字振荡器电路的分析比较基础上,基于振荡器的基本工作原理,结合比较器技术,利用与电压无关的偏置,提出了一种新型高性能的RC振荡器。电路利用UMC 0.6μm 30 BCD工艺库和Hspice进行模拟与仿真,结果表明该电路与传统的振荡器相比具有精度高、不受输入电压变化影响的优点。
Some usual oscillator circuits are introduced and compared in this paper. A novel high-accuracy RC oscillatorbased on the theory of the available RC oscillator is discussed and improved. This ciricuit is designed in the basis UMC 0.6μm 30 BCD process,its performance have been verified by Hspice simulation reach the expectancy of lower power and high-accuracyand.
