نویسندگان
چکیده
A current mirror (CM) based on self cascode arrangement, useful for low voltage analog and mixed mode circuit is proposed. The CM uses 4 MOSFETs, has high input and output swing, operating at ± 0.5 V supply. Pspice simulations confirm the high performance of this CM having a bandwidth of 2.1 GHz. Resistive and capacitive compensations result in about threefold bandwidth increase to 6.1 GHz.
