چکیده	In this paper, a new adaptive biased low voltage cascode current mirror with high input/output swing is presented. This advantage is achieved using a self-biasing transistor and compensation resistor. The new structure profits from better input dynamic range and lower supply voltage without frequency response limitation and increasing input impedance. Also, the proposed current mirror is incorporated in folded cascode amplifier in order to enhance its phase-margin. The simulation results in 0.18 μm CMOS technology confirm the theoretical analysis and exhibits 478μA linear input/output current swing and a phase-margin enhancement of 12o for the proposed current mirror and amplifier compared to the conventional circuits, respectively.
