在自动控制仪表中,常常需要使用具有乘除法运算功能的元件.采用分立元件和运算放大器的组合,以便构成具有乘除法运算功能的电路,可有许多种形式,其中比较简单而又适宜于单片集成化生产的是“变互导式”.本文对于这种形式的具有四象限运算能力的模拟乘除法电路,进行了一定的理论分析,在这一基础上,提出了一种采用分立元件安装的具体方案,这种方案同样也适用于单片集成化电路的研制.
In automatic control instruments, it is often necessary to use an element that has a multiplication and division function.With a combination of discrete components and operational amplifiers to form a circuit with multiplication and division, there are many forms, one of which is relatively simple and suitable for single Integrated production of the film is “transconductance.” In this paper, with a four-quadrant computing ability of the analog multiplication and division circuit, conducted a theoretical analysis, on this basis, proposed a discrete component Specific programs installed, this program also applies to the development of monolithic integrated circuits.
