多功能(Multifunction)模拟运算电路(以下简称“多功能电路”或“MFC”)是一种由运算放大器和晶体管组成的非线性模拟运算器。它具有三个输入端和一个输出端,通过电路中一电位器的选置,能以较高的速度和精度在较宽的动态范围内进行单象限的乘、除及幂运算;并且有电路简单,温度稳定性好等特点。因此,多功能电路很适于在自动控制,参数测试,模 The Multifunction Analog Operation Circuit (“Multi-Function Circuit” or “MFC”) is a non-linear analogue operation unit composed of an operational amplifier and a transistor. It has three inputs and one output. With the selection of a potentiometer in the circuit, single-quadrant multiplication and division can be performed over a wide dynamic range with high speed and accuracy. There are circuits Simple, good temperature stability and so on. Therefore, the multi-function circuit is suitable for automatic control, parameter testing, mode
