在现代的静电计中,前置放大器输出端就是这样的一个节点,并可以用来降低电缆泄漏的影响,如图2 - 5所示。
In modern electrometers, the preamplifier output terminal is such a point, and can be used to reduce the effect of cable leakage, as shown in Figure 2-5.
将静电计置于电压模式,然后打开外部反馈,就把反馈电路从内部网络切换到连在前置放大器输出端的外部反馈网络上。
Placing the electrometer in the volts mode and then enabling external feedback switches the feedback circuit from an internal network to a feedback circuit connected to the preamp output.
这种技术在不需要增加功耗的基础上,通过把输出端的失调电压转移到差分放大器的其他节点,从而达到减小输入参考的失调电压的目的。
The technique transfers the offset voltage from the output to other parts of the differential amplifier and can greatly reduce the input-referred offset voltage without extra power consumption.
除此之外,调试人员还应将电磁波滤波器连接至音频放大器音频输出端,诸如铁氧体磁环均能达到类似的过滤效果。
Apart from this step, designers should also connect an EMI filter, such as a ferrite bead , to the output of the amplifier.
只要制造商不是评价的放大器,其输出功率在此截断的国家,放大器通常被称为A级,单端。
As long as the manufacturer isn't rating the amplifier for its output power in this clipped state, the amplifier would normally be called class a, single-ended.
这里,我们通过旁路电容直接在运算放大器的输出端旁路。
In this case, you might want to place bypass capacitors directly on the output of an op amp.
你可以运用第一个放大器从sr785的输出端从直流电分离出来并提供正弦输出并提供正弦输出。
Here, you use the first amp to isolate the output port of the SR785 from the dc bias and provide the sinusoidal output.
