摘要
以高精度斩波稳零运算放大器TLC2652和四阶开关电容滤波器TLC04为主要器件设计了高性能的实用直流放大器;同时为了检测设计的可行性,设计了数字可调信号源和基于“零电位”法的检测电路。实验表明所设计的直流放大器具有很高的性价比。
This paper presents the design of a practical direct current amplifier of the high-performance based on high-precision TLC2652 chopper-stabilized operational amplifier and TLC04 fourth-order switched-capacitor filter, and designs the digital alterable signal source and the detecting circuit according to the “Electrical null” to detect the feasibility of the design. Low cost and high quality is proved by experimental results.
