Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.
在测量高电阻源时要考虑的另一个问题是电压表的输入偏置电流。
As shown in Figure 2-2, the input bias current (IBIAS) develops an error voltage across the source resistance (RS).
如图2 - 2所示，输入偏置电流(IBIAS)在源电阻(RS)上产生了误差电压。
The input bias current flows at the instrument input due to internal instrument circuitry and the internal bias voltage.
仪器内部电路和内部的偏移电压会在仪器的输入端引起输入偏置电流。
Again, consider using AMPLIFIERs that exhibit a smooth input bias current transition throughout the applied input common-mode voltage.
再者，所用的放大器也要考虑在加到输入端的整个共模电压(范围内)输入偏置电流转换保持平滑。
The combination of low offsets, low noise, very low input bias currents, and high speed make these amplifiers useful in a wide variety of applications.
低失调、低噪声、极低的输入偏置电流和高速度特性相结合，使这些放大器适合各种应用。
Input offset current is the difference between the two input bias currents and this leads to offset errors in in-amps when source resistances in the two input terminals are unequal.
输入失调电流是两个差动输入端的基极输入电流，当两个输入端的源阻抗不相等时，它可引起仪表放大器的失调误差。
Although input bias current is a common source of this type of error, currents generated by external circuits can also result in errors due to voltage drops across the source resistance.
虽然输入偏置电流是这种误差的常见来源，但是外电路产生的电流在源电阻上形成的电压降也能引起误差。
Otherwise, the sensor's capacitance and the amplifier's input-bias-current resistors impose a phase shift on the signal you apply to the instrumentation amplifier.
否则，传感器电容和放大器的输入偏置电流电阻，对仪表放大器的信号施加相位偏移。
You must carefully choose insulation and apply guarding potentials, and you must use an amplifier with picoampere input-bias currents.
必须谨慎选择绝缘方法和使用保护电位，必须使用输入偏置电流为微微安级的放大器。
