ABSTRACT:
A circuit for generating a reference current, comprising a positive feedback loop, a negative feedback loop, and a floating current mirror coupled to the positive feedback loop. The negative feedback loop may operate to divert current directly from the floating mirror, and may also operate to divert current from the floating mirror by using a voltage follower. The circuit may operate with a minimum supply voltage of approximately the sum of the threshold voltage of a transistor plus three drain saturation voltages, in one example.
