一引言近年来,由于通讯、雷达及各项电子工程的发展,对集成电路尤其是对线性集成电路提出了更高的要求,加上工艺的不断改进,使线性电路有了很大的发展。RCA公司、美国的国际半导体公司、HP公司、得克萨斯仪器公司、日本电气、东芝公司及英国的普莱赛公司都投入了大量的人力和物力进行研究。各个厂家都在力争研制新的品种和增加产量,同时扩大用途。目前,线性电路的发展具有以下特点: 第一,品种多、集成度高;除了各种运算放大器及锁相环路、接口电路以外,还有差分
I. INTRODUCTION In recent years, due to the development of communications, radar and various electronic projects, higher demands are placed on integrated circuits, especially for linear integrated circuits. Coupled with the continuous improvement of processes, linear circuits have been greatly developed. RCA, the United States International Semiconductor, HP, Texas Instruments, Japan Electric, Toshiba and Britain’s Plesay have invested a lot of manpower and material resources to conduct research. Various manufacturers are striving to develop new varieties and increase production, while expanding its use. At present, the development of linear circuits has the following characteristics: First, variety, high integration; In addition to a variety of operational amplifiers and phase-locked loops, interface circuits, there are differences
