Abstract

A circuit includes a comparator, a programmable current source, and a control circuit. The comparator is operable to compare an internal supply voltage of the circuit to a reference voltage. The programmable current source is operable to supply a first current for the reference voltage. The control circuit is operable to control the first current through the programmable current source based on an output signal of the comparator.
