偏置电流源电路的设计：利用带隙基准电压源提供的，通过运算放大器为系统其他的模块提供一个与温度无关的稳定的电流偏置。
The current bias design: Taking advantage of the bandgap reference voltage, the temperature independent current bias for the system is designed by an operation amplifier.
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。
Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.
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。
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.
