ABSTRACT:
In a reference current generator, a current mirror has a referent branch with a first current flowing thereon and a mirror branch to produce a second current by mirroring the first current, a first transistor is coupled to the referent branch, a second transistor is coupled to the mirror branch and has a gate coupled to the gate of the first transistor, one or more third transistors each produces a reference current by mirroring the first current or the second current to supply for a load, and a resistor having a resistance proportional to the absolute temperature is coupled to the first transistor such that a third current equal to the summation of the first current and all the mirrored reference currents flows through the resistor.
