Abstract: A temperature-sensing device configured to monitor a temperature includes: a first conductive line; a second conductive line, wherein the first and second conductive lines have respective different cross-sectional dimensions; a sensing circuit, coupled to the first and second conductive lines, and configured to determine a logic state of an output signal based on a difference between respective signal levels present on the first and second conductive lines; and a control circuit, coupled to the sensing circuit, and configured to determine whether the monitored temperature is above or below a pre-defined threshold temperature based on the determined logic state.
