A novel CMOS cascode current mirror configuration with enhanced input dynamic range is presented. The proposed mirror circuit combines the advantages of wide input swing, wide output swing and large output resistance capability, which make it attractive for practical application. Based on 0.18 µm MOS model parameters, HSPICE simulation results show that the input current ranges from 1 µA to 1 mA with large bandwidth for the proposed circuit. The simulation results confirm the theoretical prediction. Copyright © 2009 John Wiley & Sons, Ltd.
