摘要
对电压测量电路的基本要求是其应具有高输入阻抗,文章设计了几种实用的电压测量电路,即场效应管差分式电路、高阻型集成运放构成的电路、高稳定度与高增益集成运放构成的电路。这些电压测量电路具有很高的输入阻抗,因而可有效地减小测量误差,提高准确度。
Voltage measurement circuit is the basic requirement should have a high input impedance. Several practical voltage measurement circuit design, is FET differential circuit, high-resistance of integrated operational amplifier circuit, consisting of high stability posed by integration with high-gain amplifier circuit. These voltage measurement circuit with a very high input impedance, thus effectively reducing measurement error, increase accuracy.
