摘要：建立运算放大器引入了一个新的基本组成部分，标志着模拟设计师的思维变化。因为它是如此广泛的应用，几乎任何运放电路，工程师需要实现已经被设计工程师可以只是裁缝的元件值。这种方法虽然快速，并不总是意味着设计师电路的操作理论的一个基本的了解。本应用笔记介绍如何可以通过简单的节点分析过程中所产生的大多数运放电路的传递函数。Maxim > App Notes > AMPLIFIER AND COMPARATOR CIRCUITS

APPLICATION NOTE 1939
Nodal Analysis of Op Amp Circuits
Abstract: The creation of the op amp introduced a new fundamental component and marked a change in
thinking for analog designers. Since it is so widely used, pretty much any op amp circuit that an engineer needs
to implement has already been designed and the engineer can merely tailor the component values. This
approach, although quick, does not always mean the designer has a fundamental understanding of the theory
of the circuit operation. This application note explains how the transfer function of most op amp circuits can be
derived by a simple pro……
