differential operational amplifier meaning in English

差分运算放大器

In the fifth chapter , a new fully differential operational amplifier with voltage and current - mode negative feedback has been proposed , which can stabilize its quiescent operation point , using the characteristic of mos transistors which operate in the triode region acting as active variable resistor , a fully differential fourth - order chebyshev low - pass filter with tunable frequency and bessel low - pass filter with accurate group delay based on r - mosfet - c and operational amplifier has been designed
第五章：提出了一种新的既具有电压共模负反馈又同时具有电流共模负反馈的全差分运算放大器电路，能较好地稳定电路的静态工作点，并应用mos管工作在线性区可作有源可变电阻用的特性设计得到了截止频率可连续调节的高性能r - mosfet - c 、运放结构切比雪夫( chebyshev )和精确群时延值贝塞尔( bessel )低通滤波器。
