Abstract
An apparatus is described. The apparatus according to an embodiment includes a voltage dividing resistor circuit formed on a semiconductor substrate and including first and second resistors and first and second selector switches. The first and second resistors and the first and second selector switches are arranged with one of first and second layouts. The first layout is such that the first and second selector switches are placed between the first and second resistors. The second layout is such that the first and second resistors are placed between the first and second selector switches.
