Abstract
Class AB amplifier is widely used as analog building blocks for many applications. The recent development of class AB amp for low power and low voltage applications is reviewed and summarized. A low noise design realization is fabricated in 0.35 um CMOS technology. For 10pF cap load, it shows GBW of 800KHz with supply voltage of 2.5 V and about 5uA quiescent current.1
