摘要
差动放大电路是一种应用电路构造参数的对称性有效抑制"零点漂移"的放大电路。本文首先对差分放大电路的原理进行阐述,然后用仿真分析法对恒流源差分放大电路的工作性能进行仿真分析和计算,得出与理论分析相符合的结果,从而加深了对差分放大电路工作原理的理解。
Differential amplifier is a circuit to effectively inhibit ＂zero drift＂ by using the symmetry of circuit structure parameters. This paper describes the principle of differential amplifier circuit, then makes some simulation analysis and calculation on the properties of differential amplifier circuit with constant-current source, and obtains the result compatible with theoretical analysis, which deepens the understanding on the principle of differential amplifier circuit.
