  author={D. Kushwaha and D. Mishra},
This paper proposes a low voltage CMOS Nano power current reference circuit and presents its performance with circuit simulation in 180nm UMC CMOS technology. The proposed circuit consists of start-up, Bias-voltage, currentsource sub-circuits with most of the MOSFETs operating in sub-threshold region. Simulation results shows that the circuit generates a stable reference current of 4-nA in supply voltage range 1 V1.8 V with line sensitivity of .The temperature coefficient of the current was at… Expand
