摘要
为了详细分析目前比较常用的555定时器和运放构成的矩形波发生器,填补其他文章仅单单分析一种电路的空白,利用Multisim强大的仿真分析功能,结合理论计算,对这两种方波发生器进行输出电压特性、占空比调节、输出频率、电源电压范围等方面的比较分析,希望给制作矩形波发生器的读者提供一定的参考价值。
In order to analyze the current commonly used 555 timer and the op-amp configuration square wave generator in detail, and to fill the empty of other papers which only analyze one circuit alone, this article uses the powerful Multisim simulation analysis capabilities to carry out comparative analysis of these two square wave generator form output voltage characteristics, duty cycle regulation, output frequency, supply voltage range and other aspects combined with theoretical calculations. The author hopes to provide reference for readers making rectangular wave generator.
