能对运用范围和灵敏度进行独立调节的四象限乘法器

The Four-quadrant Multiplication That Can Separate Adjustment to Applied Range and Sensitivity

本文研究了一种设计条件独立于输入的,应用场效应管的改进型模拟乘法器。这种乘法器在交直流工作时都能进行四象限相乘,而且还能实现对范围的单独控制,克服了范围受限问题,而且乘法器的输出是独立可控的。

This paper designed an analog multiplication that unaided to input and applying field-effect transistor. This multiplication can do four-quadrant multiplication in double current, achieve separate control to scope, overcome scope limited, the output for multiplication is separate and controlled.
