Since its unique manufacturing technology, the MEMS geophone has ultra-low noise, larger dynamic range and very high vectorial fidelity performances. 因其独特的制造技术,MEMS检波器具有超低噪声,大动态范围和极高的向量保真度性能。
To the ultra-low speed 、 high-frequency and wide-speed range performance index of electro-hydraulic simulator, the paper analyze the theory and structure designing of middle hollow electrohydraulic servomotor. 针对液压仿真转台提出的超低速、宽调速、高频响等性能指标,文章对中空电液伺服马达进行了理论分析和结构研究。
Based on the structure, an ultra-low voltage operational amplifier is designed, which provides a rail-to-rail common-mode input voltage range and output voltage swing, as well as a high common mode rejection ratio ( CMRR ). 基于此结构,实现了一种超低压运算放大器。仿真分析表明,该运算放大器能够实现轨到轨(rail-to-rail)的共模输入电压范围和输出电压摆幅,以及较高的共模抑制比。
To realize low / ultra-low sidelobes, conventional phased array antennas usually require the amplitude excitations with large dynamic range ratios. 常规天线阵为了实现低副瓣或超低副瓣必然要求阵列天线馈电具有很高的幅度动态范围比。
