| 摘 要： | 设计了一种新颖的CMOS无稳态多谐振荡器,克服了传统设计中时钟占空比依赖于工艺参数的缺陷.改进的设计不仅能产生占空比为50%的时钟信号,而且能有效地预防电路闩锁.所有的改进几乎不增加电路的动态功耗,因此新设计有广泛的工程应用前景.

| Abstract: | An improved on-chip CMOS astable multivibrator is proposed, which overcomes the shortcomings of the traditional one that the signal duty-cycle is depending on model parameters, and generates stable clock signal with duty-cycle equaling 50%. The latch-up effect has been prevented on the improved circuit. It is extremely important that all the excellent performances of the improved astable multivibrator have been achieved with a dynamic power consumption equaling its predecessor one. The advantage of the structure has been verified by SPICE simulation. |
