Abstract :
A modified regulated cascode structure having high output swing capability is presented. This structure is used in the implementation of a current mirror. The current mirror possesses wide input and wide output swing capabilities, suitable for low voltage operation. P-SPICE simulations at 0.25 ¿m CMOS technology validate the proposed current mirror for currents from 30 nA to 220 ¿A, at 1 V with 1.5 GHz bandwidth, 0.2 mW power dissipation at 100 ¿A and current transfer ratio of 1 within ±0.5% error. The output impedance of the current mirror is extremely high (2.5 G¿).
