초록

This paper proposed the new current feed-back amplifier for low supply voltage application. The input stage was designed to be a class-AB circuit and achieve the low supply-voltage operation down to $2V_{TH}+2V_{DS(SAT)}$. With the self-adjust bias current, the high performance can be adopted with high stability. The circuit was successfully proven by the simulation with MOSIS 0.5 ${\mu}$m MOS technology.
