Abstract
An out-of-band (OOB) detection circuit includes: a positive input node; a negative input node; a resistive circuit comprising a first resistor coupled between a first supply node and a first node, a variable resistor coupled between the first node and a second node, and a second resistor coupled between the second node and a ground; a first comparator configured to compare a difference between a positive input signal received at the positive input node and a negative input signal received at the negative input node against a positive threshold value, and a second comparator configured to compare the difference between the positive input signal received at the positive input node and the negative input signal received at the negative input node against a negative threshold value.
