测量放大器抗共模干扰分析
Measurement of anti-amplifier common-mode interference analysis
测量放大器能够用于放大微弱信号，具有高输入阻抗、低输出阻抗、低温漂、低失调电压和高稳定增益等特点。由于测量放大器直接放大微弱信号，对其共模抑制性能有较高的要求。本文分析了测量放大器的主要性能指标，即抗共模干扰的产生原因，研究了如何提高抗共模干扰能力。
Measuring amplifiers can be used for amplification of weak signal, with a high input impedance, low output impedance, low drift, low offset voltage and high gain stability and so on. Measured directly as a result of amplification of weak signal amplifier, common-mode rejection performance of their higher requirements. This paper analyzes the performance measurement indicators of the main amplifier, that is, anti-common-mode interference causes studied how to improve the ability of anti-common-mode interference.
