第四节

非线性有源电路的设计


Ch4s4 2

电压比较器的设计

ch4s4-2

阀值检测器


Ch4s4 3

窗口检测器

ch4s4-3


Ch4s4 4

反相施密特触发器的设计

ch4s4-4

同相施密特触发器的设计


Ch4s4 5

阀值带偏移的反相施密特触发器

ch4s4-5


Ch4s4 6

阀值带偏移的同相施密特触发器

ch4s4-6


Ch4s4 7

小信号整流器的设计

ch4s4-7

半波整流

全波整流


Ch4s4 8

二极管及其非线性电阻特性

ch4s4-8

有源小信号半波整流电路

缺点:运算放大器交替工作在线性放大区和饱和非线性区,

转换是需要时间的,对高速输入信号可能会造成失真。
