A compact low-power supply-insensitive CMOS current reference
2012
2012 IEEE International Symposium on Circuits and Systems
A simple low-power current reference using dualthreshold MOS transistors is introduced. The area required for this reference is small and the sensitivity of the output current to the supply voltage is low. Simulation results show that an implementation of this current reference in a TSMC 0.18um CMOS process with a 1.8V power supply is constant to within ±1.25% over the temperature range of -10 C to 100 C. In this implementation, the active area is 86 µm 2 , the power dissipation is 72µW, and
