drag-lift coefficient

That is to say when self-elevate resistance Rg meets low noise condition,the circuit noise disadvantage effect will decrease to minimum and then overlook it.

即:当自举电阻Rg满足低噪声化条件时,自举电路对原电路噪声的不利影响就可以减到最小而可以忽略不计。

Introduce several typical application amplifier: basic reverse proportion amplifier,reverse amplifier with high impedance made up of T meshwork,reverse amplifier with booster high impedance,basic differential amplifier;differential amplifier of high radical mode bound.

并介绍几种典型的应用放大器:由цA741组成的基本放大器、T型网络高输入阻抗放大器、自举高阻反相放大器;基本差动放大器;高基模范围的差动放大器。
