We don't fudge or enhance what our amplifiers can do, they simply hit hard all the time.

我们不捏造或加强我们的放大器什么可以做，他们只是沉重打击所有的时间。

There is no need to go to the expense of monobloc power amplifiers in order to keep crosstalk under control, even when making it substantially better than the 20dB that is actually necessary.

没有必要为了控制色度亮度干扰而花大笔的钱在广播功放上，即使是使它比20分贝更好。

Power for the tractor beam emitters is provided by variable phase graviton polarity sources feeding sub-cochrane subspace field amplifiers. Phase accuracy of less than 2.7 arc-seconds per millisecond is required for precise control of a tractor beam.

牵引光束发射器的动力供给是靠子空间的Sub-Cochrance范围放大器，来供给牵引光束使用的可变相位极性，为了要正确地控制牵引光束的相位正确性要求，因此其相位变化必须少於每毫秒的2.7弧秒。

此外，还改进了掺铒光纤参数的测量方法，减少了参数测量的系统误差。

In the AMB system, the load is an inductance coil,traditional power amplifiers are notsuited for this application.

磁浮系统的负载为电感线圈，普通的线性功率放大器效率低不能满足上述要求，为此作者设计了带电流负反馈的PWM型功率放大器。

It is shown from the accelerated lifetime test and noise measurement for integrated operational amplifiers that if their failure is caused by the drift of input bias current or input offset current, the drift is strongly correlated with 1/f noise current in these devices, and both are proportional approximately.

摘要寿命试验和噪声测试结果表明，如果集成运算放大器的主要失效模式是输入偏置电流或失调电流随时间的漂移，则这种漂移量与运放的1/f噪声电流具有强相关性，二者近似呈正比关系。

The amplifiers chosen must be compensated for unity-gain operation and R6 and R7 must be chosen to minimize output errors due to input offset current.

注释 2：(NE5532 注) R4U i =0 R3 首先，对节点处的电流讨论是没有意义的，流入节点的电流一定等于流出节点的电流，再者，I3 与 I4 不是等大反相的关系，分析如下： 40 An Applications Guide for OP Amps 由于此时 OPA1 处于反相放大状态，其输出电压 U o1 压误差按照设计思路，此时 A2 的输出应该等于 U o1 ，则电流方向如上图。
