Abstract: In examples, an apparatus includes a FET, first and second voltage-to-current circuits, a current selection circuit, and a comparator. The FET has first and second segments. The first segment has a first gate coupled to the first voltage-to-current circuit, a first source, and a first drain. The second segment has a second gate coupled to the second voltage-to-current circuit, a second source coupled to the first source, and a second drain coupled to the first drain. The current selection circuit has a current selection circuit output and first and second current selection inputs. The first current selection circuit input is coupled to the first voltage-to-current circuit. The second current selection circuit input is coupled to the second voltage-to-current circuit. The comparator has a comparator output and first and second comparator inputs, the first comparator input is coupled to the current selection circuit output.
