相敏放大器是被广泛用于各种不同的自动调节和自动控制系统中,它是用来改变交流信号电压为直流输出,并要求输出直流电压之极性随交流信号电压之相位改变180°而改变.本文对此电路提出一种简单的图解分析法,对并联电阻一电容负载差动式相敏放大器进行定量计算,并和В.И.Анисимов的动态计算方法~[1]取同样的假定条件,构成一简单的静态计算方法.文中提出了对典型放大电路如何定出电路的静态工作点;以及如何在等
Phase sensitive amplifiers are widely used in a variety of automatic adjustment and automatic control systems. They are used to change the AC signal voltage to a DC output and require that the polarity of the output DC voltage be changed by 180 ° with respect to the phase of the AC signal voltage Change.This paper presents a simple graphical analysis of this circuit, the parallel resistance of a capacitive load differential phase-sensitive amplifier for quantitative calculation, and the dynamic calculation of В.И.Анисимов ~ [1] to take the same assumption Conditions, constitute a simple static calculation method. The paper proposed how to determine the typical circuit of the static amplifier operating point; and how to wait
