摘　　要：尽量消除或抑制电子电路的干扰是电路设计和应用始终需要解决的问题。传感器电路通常用来测量微弱的信号,具有很高的灵敏度,如果不能解决好各类干扰的影响,将给电路及其测量带来较大误差,甚至会因干扰信号淹没正常测量信号而使电路不能正常工作。在此,研究了传感器电路设计时的内部噪声和外部干扰,并得出采取合理有效的抗干扰措施,能确保电路正常工作,提高电路的可靠性、稳定性和准确性。Try to eliminate or suppress the interference of electronic circuit is a key problem that the circuit design and ap- plication should be solved. Sensor circuit with high sensitivity is usually used to measure the weak signal, if all kinds of inter- ference can＇t be solved, it will bring great error for the circuit measurement, and even the circuit does not work due to the nor- mal measuring signal is submerged by interference signal. Therefore, the internal noise and external interference of the sensor circuit design must be studied, the reasonable and effective anti-jamming measures should be adopted to ensure the circuit op- eration and to improve the circuit reliability, stability and accuracy.
