The bandgap reference uses a pre-regulator with supply ripple subtraction technique to improve its power supply rejection ratio (PSRR).
实现了一种高精度带隙基准源,该基准源在预调节电路中应用了电源行波减法技术,显著改善了输出电压的电源抑制比。
Prom the point of view of error correction, reflector dynamic error correction is discussed and calculated by applying the techniques of the best-fitting surface and rigging adjusted.
建立了40 m口径射电望远镜天线结构有限元模型,依据模型分析结果,对40 m口径射电望远镜天线主面误差进行了分析和数值计算;从误差修正的角度,分别对主面误差的最佳拟合修正、安装角预调的工作仰角综合修正进行了分析与数值计算。
