Self Cascode Current Mirrors For Low Voltage Analog Circuits
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.

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain.
