Bandwidth Extension of High Compliance Current Mirror by Using Compensation Methods
Due to the huge demand of high-speed analog integrated circuits, it is essential to develop a wideband low input impedance current mirror that can be operated at low power supply. In this paper, a novel wideband low voltage high compliance current mirror using low voltage cascode current mirror (LVC...

| description | Due to the huge demand of high-speed analog integrated circuits, it is essential to develop a wideband low input impedance current mirror that can be operated at low power supply. In this paper, a novel wideband low voltage high compliance current mirror using low voltage cascode current mirror (LVCCM) as a basic building block is proposed. The resistive compensation and inductive peaking methods have been used to extend the bandwidth of the conventional current mirror. By replacing conventional LVCCM in a high compliance current mirror with the compensated LVCCM, the bandwidth extension ratio of 3.4 has been achieved with no additional DC power dissipation and without affecting its other performances. The circuits are designed in TSMC 0.18 μm CMOS technology on Spectre simulator of Cadence. |
