Question

Note that these are similar to techniques used to stabilize
magnetic deflection amplifiers described in Apex AN #5,
“Precision Magnetic Deflection.”
CURRENT OUTPUT FOR GROUNDED LOAD
The VCCS for a grounded load is sometimes referred to
as the “Improved Howland Current Pump.” It is actually
a differential amplifier which senses both input signal and
feedback differentially.
Figure 7 shows a general example for this VCCS with its
associated transfer function.
First among the special considerations for this circuit is that
the two input resistors (RI), and the two feedback resistors
(RF), must be closely matched. Even slight mismatching will
cause large errors in the transfer function and degrade the
output impedance causing the circuit to become less of a true
current source.
As an example of the matching requirement, consider the
actual example using PA07 in Figure 8. Matching the resistors
as closely as tolerances permitted produced an output
impedance of 43 K ohms. A 1% mismatch reduced output
impedance to 200 ohms and introduced nearly 20% error into
the transfer function.

Answer 1

请注意，这些都是类似的技术用来稳定
磁偏转放大器所描述的顶点一＃ 5 ，
“高精度磁偏转” 。
电流输出为接地负荷
该vccs为接地负荷有时被称为
作为“改善豪兰目前的泵。 ”它实际上是
一差动放大器，其中感官都输入信号和
反馈的差异。
图7显示了一般的典范，这与它的vccs
相关的传递函数。
第一，其中特别考虑因素，这条赛道的是，
两个输入电阻（里） ，和两个反馈电阻
（ RF ）的，必须紧密配合。即使是轻微的错配会
造成较大的误差在传递函数和降解
输出阻抗造成电路成为少一个真正的
电流源。
作为一个例子，匹配的要求，考虑
实际的例子使用pa07在图8 。匹配电阻
作为紧密合作，作为公差允许的制作，输出
阻抗43 k欧姆。 1 ％的错配减产
阻抗200欧姆，并介绍了近20 ％的错误到
传递函数。

喊~~上面全是机翻的~~
要获得满意的翻译，我建议你把这段文分成10份，每份出10分，就会有很多人帮你人工译的。这是我个人的经验，因为我发现那些一大段的文章，比较不受欢迎。大家都比较懒得去人工译，所以通常得到的全都是机器译的。万一最后来个投票。。。功夫就白费了。。。这只是我的些建议，希望对你有帮助。
