摘要
通过对铯束管信号特性以及噪声的分析,采用高精度运算放大器OPA128LM,设计了一种可用于铯束管信号测量的放大滤波电路,并且根据需要设计了微电流源,运用Protel电路仿真软件进行仿真调试,使其达到设计要求。
A rapid micro-current amplifier is presented to measure the signal of CBT by analyzing signal characteristic and noise of cesium beam tube with magnetic state selection,which is based the high-precision OPA128LM.Then,a micro-current source was designed and the circuit was debugging by the Protel software.In the end,the simulation result shows that the micro-current source satisfied the design demand.
