ABSTRACT:
A current reference circuit, for generating a reference current from a low voltage supply source, includes a first n-channel field effect transistor (NFET) having a gate and a drain that are coupled together, and a grounded body; and a second NFET having a floating body, and a gate coupled to the gate of the first NFET.
