发帖数: 257 | 1 我设计了一个单位增益的电压buffer 供电电压（+12~-12） 用的结构很简单 差分对加
class AB output stage 发现接成单位增益的buffer（电压跟随）之后摆幅不够 最大
只有到正负 4v 输入信号如果到了正负5V以上 我的电压跟随器就跟不上了 信号都被砍

发帖数: 489 | 2 you are likely experiencing slew rate limiting. essentially the amp isn't
fast enough for your singal.
if 0db is all you need, try a diamond buffer (four transistors), or buf634/
opa551 or their equivalent (buf634 is out of production i think). |
