集成电路所用的元件具有较大的公差和温度系数已为人们所熟知。本文集中研究应用单块结构所提供的优点来进行的设计原理。这些优点为:参数的紧密匹配与跟随,元件几何尺寸的控制,以及可使用成本极低的大量有源器件。用了这些技术,在很多情况下能够与分离元件线性电路的性能相匹敌,甚至超过。 It is well known that components used in integrated circuits have large tolerances and temperature coefficients. This article focuses on the design principles that apply to the advantages offered by a monolithic structure. These advantages are: close matching of parameters and follow-up, control of component geometry, and the availability of a large number of active devices at very low cost. With these techniques, in many cases the performance of a linear circuit that separates the components can be matched or exceeded.
