Principle and Analysis of the Chopper Controlled Gain Amplifier 斩波式可控增益放大器原理及分析
A magneto-optical Kerr effect ( MOKE) setup with the sensitivity of about 1 nm was assembled using He-Ne laser, chopper, polarizer, photodiode, lock-in amplifier, electro-magnet and industrial computer. 利用He-Ne激光器、斩波器、起偏/检偏棱镜、光电探测器、锁相放大器、电磁铁、工控机搭建了一台分辨率在1nm左右的磁光Kerr效应装置。
A three-stage pipeline chopper inverter phase amplifier, capacitive interpolation and pre-equalized comparator are utilized to achieve high speed and low power. 该A/D转换器应用三级流水的斩波反相放大器、电容插值结构和预平衡的比较器,以实现高速、低功耗。
The hardware part includes He-Ne laser, two coaxial stages, photoelectric detector, chopper and lock-in amplifier. And the sapphire prism, sensor chip and mechanical structure of the sampling system are designed all by ourselves. 硬件部分主要包括He-Ne激光器,两轴转台及控制器,光电探测器、斩波器和锁相放大器等,并自行设计加工了蓝宝石棱镜,传感芯片,棱镜固定架及流通池系统。
