1.概要作为模拟电子计算机的基本元件研究的运算放大器,总是从理想放大器的各个角度出发考虑问题。目前,混合的和单块的都得到迅速发展。并且,电路设计,器件和制造技术有机地联系在一起。混合集成电路和高密度组装等,具有批量生产性能,价格低,非常容易使用,应用范围在继续扩展。但是,为了适应多种目的的要求,运算放大器已经实现了集成电路化。现在不仅仅适用于电子计算机,实际上已经成为电子学的一种基本电路元件。运算放大器从结构上可分为单块和混合两种,共500～600种,其中混合型
1. Overview As the basic components of analog electronic computer research op amp always consider the problem from all angles of the ideal amplifier. At present, mixed and monolithic have been rapidly developed. And circuit design, device and manufacturing technology organically linked together. Hybrid integrated circuits and high-density assembly, with mass production performance, low price, very easy to use, the scope of application continues to expand. However, in order to meet the requirements of a variety of purposes, op-amp has achieved integrated circuit. Now not only for electronic computers, in fact, has become a basic electronic circuit components. Operational amplifier from the structure can be divided into two kinds of monolithic and mixed, a total of 500 to 600 kinds, including hybrid
