Abstract
According to an aspect, a comparison circuit includes (A) a comparator to compare a comparator input with a comparator reference and generate a comparator output; (B) a mode selector to generate as a mode value, a first logic value if an input voltage (provided at a first node) is below a mid-voltage and a second logic value otherwise; (C) a first branch (coupled between the first node and a second node) to generate a first voltage drop approximately equaling a difference between a first reference voltage and the comparator reference; (D) a second branch (coupled between the first node and a second node) to generate a second voltage drop approximately equaling a difference between a second reference voltage and the comparator reference; and (E) a selection circuit to couple one of the second node or the third node as the comparator input according to the mode value.
