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 develops an error voltage across the source resistance.

如图2-2所示，输入偏置电流在源电阻上产生了误差电压。

These two pairs exhibit different offsets and bias currents, so when the applied input common-mode voltage changes, the AMPLIFIER input offset voltage and input bias current does also.

由于这两个差分对有不同的失调电流和偏置电流，因此加到输入共模电压变化，放大器的输入偏置电压和输入偏压电流也跟着改变。

The driver stage function obtains enough high voltage amplification factor, as well as the output stage provides enough big drive current, for this reason, may use the belt collection electricity level altogether to shoot the amplifying circuit, its static bias current ratio input level must be big.

推动级的作用是获得足够高的电压放大倍数，以及输出级提供足够大的驱动电流，为此，可采用带集电级的共射放大电路，其静态偏置电流比输入级要大。

The amplifier has additional modulation and demodulation,and has the advantage of smaU input bias current, low maladjustment voltage and temperature excursion, exact feedback speciality and high common mode control ratio.

具有输入偏置电流小，低失调电压和温度漂移以及精密的反馈特性和高的共模抑制比能力。

This current is known as the input offset current, and it is caused by bias currents of active devices as well as by leakage currents through insulators within the INSTRUMENT .

这个电流就是输入失调电流，它可能是由有源设备的偏置电流引起的，也可能是由仪器内的绝缘体泄漏电流引起的。

S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

接着 S1 拨到位置 1，使 C1 的电压加在放大器的输出端和反相输入端之间，(由于电容端电压不能突变，所以)输出端的电压将产生大小等于 VIN 的变化，使放大器输入端维持输入失调电压，即当开关 S1 从位置 2 拨到位置 1 时，输出端电压将从(VOS + IbiasR2)变为(VIN + IbiasR2)。S1 处于位置 2 时，放大器的偏置电流是由输出端经电阻 R2 提供的，当 S1 转向位置 1 时则由 C2 提供。R3 的作用是降低输出失调电压，如果要求放大器具有最大的线性范围，或者采用直流耦合，就应该使用该电容。

Operational Tran conductance lifers and Grounded actorhas become one of the most important methods to implement integrated continuous-time filters. Operational Tran conductance Amplifierscan transfer input voltage into current to output,and control or change output current within large range by an external controlling current of amplifier. Most articles consider OTA as a voltage-mode circuit component and give voltage-to-voltage transfer function of all having been implemented filter circuits,i.e. The input signal and output signal of filter circuits are voltages .

运算跨导集成运算放大器OTA ( Operational Tran conductance Amplifier 以下简称跨导运放)的功能是将输入电压转换为电流输出，并通过外加偏置电流控制运放的工作电流，从而使它的输出电流在较大范围内变化，而在大多数文献中，器件都被作为电压模式元器件使用实现的各种滤波电路都是按传送电压比给出的，即滤波电路输入信号和输出信号均为电压信号。
