摘要
在现代测控系统中,经常会用到程控放大器(PGA),由于PGA必须具有可以实现自动调节增益的功能,因而其精度总会因使用一些调节元器件而受到影响。本文阐述了几种PGA的设计方法,在提高PGA的精度方面提出一些观念,并通过实验和使用对所设计的电路做了验证。
In the system of modern measure and control, the programming gain amplifier (PGA) is frequently used. As PGA has to realize the function of modulation of plus automatically, its precision will be kind of affected by some components. This article sets forth several design of PGA, brings forward some new point of view about improving its precision, and verifies those circuits by experiment or application.
