ABSTRACT:
Circuits and methods are provided for generating reference currents. In one implementation, a circuit is provided that includes a first source and a current control circuit in communication with the first source. The first source generates a first reference current that is a ratio of a first reference voltage and an external resistance. The current control circuit produces a second reference current that is a ratio of a second reference voltage and the external resistance. The current control circuit produces the second reference current without being directly coupled to the external resistance.
