关于具体的Class-AB output stage的实现方法,大致可以分为四类: 1. Cross-coupled quad 形式连接的super-source follower结构 2. 从低阻抗节点驱动一个或全部输出管,并用反馈控制输出管静态电流 3. 通过local class-AB 反馈来控制静态电流 4. 通过translinear loops的方法 **关于cross-couple quad的结构一般多用于...
Actually many class AB output stage design utilises a minimum current selector in both bipolar and MOS processes. This head-to-tail coupling design is the most elegent one. The important feature is that no output transistors (M25, M26) are completely turned-off, improving the speed and stabil...
