Abstract
a low voltage CMOS Nano power current reference circuit has been presented in this paper and also the circuit simulation performance in 180-nm UMC CMOS technology. Most of the MOSFETs operate in sub-threshold region consisting of bias-voltage, start-up and current-source sub-circuits. A stable reference current of 4-nA lying in supply voltage range of 1 V-1.8 V has been generated with line sensitivity of 0.203% /V. Within the temperature range of 0°C to 100 °C, and the voltage level of 1.8 V, the temperature coefficient was 7592ppm/°C. At the same voltage supply, the power dissipation was found out to be 380 NW. It is suitable to use this circuit in sub threshold power aware large scale integration.
