【摘要】 在构成基本型电阻电桥传感放大器的基础上给出了三种改善其性能的方法。1)补偿法。2)补偿加放大器改进综合法。3)负反馈法。通过实验证明了理论分析和实际效果是一致的,从而对电阻传感器在非电量检测中的广泛应用具有一定的实际意义。更多还原

【Abstract】 Three methods used for improving resistive bridge amplifier are introduced in this paper. The first is that resistive sensor is compensated. The second is that sensor is compensated and amplifier is improved. The last one is that negative feedback is used in the circuit. Experiment results are given to support the theoretical analyses.更多还原
