Abstract
A semiconductor device including a temperature sensor includes a pull up circuit, a pull down circuit, a first additional current path, and a second additional current path. The pull up circuit is configured to generate a pull up current that contributes to generation of a first output current. The pull down circuit is operably coupled to the pull up circuit at an output node and configured to generate a pull down current that contributes to generation of a second output current. The first additional current path, when enabled, is configured to combine a first additional current with the pull up current to comprise the first output current. The second additional current path, when enabled, is configured to combine a second additional current with the pull down current to comprise the second output current. Respective enablement of the first additional current path and the second additional current path is complementary.
