Abstract

本文简要分析了现有电流源电路的原理及优缺点，并且新设计了由多路镜像电流源电路和权电阻网络所组成的模拟乘法器电路，使得多级乘法器不仅独立工作，也可以同步调节其各级的输出增益，满足了日益发展中的电子产品的应用需求。
This text briefly analyzes the principle and relative merits of existing current source circuit, and newly designed analog multiplier consisting of multiple current source cicuit and weighted resistance type that makes the multistep multiplier can not only work independently but also synchronously regulate all level's output gain, which could preferably meet the application demand of the developing electronics.
