缺点是,PMOS 成本较高。一般用于电流超过 3A 以上的大电流应用场合。 这种方式栅极驱动电路简单,且 NMOS 成本较低。其工作原理和 PMOS 类似。但由于这种防反结构使得电源地和负载地被分割,在汽车电子产品设计中,很少用到。 下面我们来详细介绍 PMOS 的防 ...
THIS book deals not with a special branch of physical science but with a general method and its applications to different problems. Its striking feature is the number and variety of subjects which ...
在电力电子中,常利用MOS管的饱和区特性将其作为负载电源开关,如下图所示: 上图电路主要由MOSFET与控制部分组成,其中MOSFET可以选择PMOS或NMOS。
其中,Vgsth为MOS管的开启电压,IDSS为Vgs=2Vgsth时,IDS电流值。 如上即为NMOS管的工作原理。 二、为什么PMOS的闪烁噪声低于NMOS 首先,闪烁噪声是指当MOSFET在静态或动态偏置下运行时由热噪声产生的频谱噪声。它的特征是随机性和高度非线性的频谱特性,同时它也是 ...
NMOS在实际应用中为何比PMOS要更受欢迎,本文将从导电沟道、电子迁移率和器件速度等多个方面来展开讲解。 首先是在性能 ...
