Abstract :
This paper describes a 1.8 V self-biased complementary folded cascode(SB-CFC) amplifier. We propose a new self biasing scheme for the folded cascode amplifier which eliminates 6 external bias voltages and related biasing circuits. The required minimum power supply voltage is reduced to 1.8 V and the output voltage swings are increased. With our new self-biasing scheme the area and power overhead, susceptibility of the bias lines to noise and crosstalk, and design time are reduced
