In this situation, the CMRR ( common-mode rejection ratio) of the input differential amplifier was unsatisfactory. 在这种情况下,输入差分放大器的CMRR不令人满意。
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。
The circuit has advantages with ingeniously conception, well structure, integrated easily, more open-loop gain, more common-mode rejection ratio and alternating current characteristic. 该电路具有构思巧妙,结构优化,易于集成及较高的开环增益,共模抑制比及交流特性的优点。
The instrument has a high common-mode rejection ratio and smallest form error among the same kind of existing profilometers. 此仪器具有很高的共模抑制比和同类型仪器中最小的形状误差。
An operational amplifier with high common-mode rejection ratio ( CMRR) is designed based on this transconductance, which provides rail-to-rail input and output. 在此基础上,设计了一种具有高共模抑制比的恒定跨导运算放大器。该运算放大器具有Rail-to-Rail的输入、输出能力。
Floating circuit improved the common-mode rejection ratio of SEMG and prevented the circuit self-excited. 引入浮地电路,提高了信号的共模抑制比,防止电路自激。
