Abstract

An integrated circuit comprising: a source comprising an output port; a set of serially-connected resistors electrically coupled to the output port of the source; a comparator comprising a first input port, a second input port, and an output port; a set of switches, each switch in the set of switches comprising a first terminal electrically coupled to the first input port of the comparator, and a second terminal electrically coupled to the set of serially-connected resistors; a current source comprising an output port electrically coupled to the second input port of the comparator; and a pin electrically coupled to the output port of the current source.
