A new low voltage highly linear FVFSC current mirror

In this paper, we have proposed a new low voltage, highly accurate Flipped Voltage Follower Self Cascode (FVFSC) current mirror which has a high input linear range and also possess high current copy accuracy. Input linear range of the proposed FVFSC current mirror has been increased to 980 μA i.e., enhanced by a factor of 2. The proposed and conventional circuits have been designed at 180nm technology node and simulated results validate the proposed approach. The current mirrors have been simulated at 1V supply voltage and 0-1 mA current range. The proposed current mirror is very useful for low voltage, wide range applications. Also, Monte Carlo simulation has been performed against resistor to prove the robustness of the circuit. Simulated results shows that the output current variations due to variations in R are very small.
