Abstract :
A high performance and compact current mirror with extremely low input and high output resistances (Rin∼0.01Ω, Rout∼10 GΩ), high copying accuracy, very low input and output voltage requirements (Vin, Vout≥VDSsat), high bandwidth (200 MHz using a 0.5 μm CMOS technology) and low settling time (25 ns) is proposed. Simulations and experimental results are shown that validate the circuit.
