Abstract:
1. A semiconductor device including at least one temperature sensor, the at least one temperature sensor comprising: a pull up circuit configured to generate a pull up current operably coupled to a pull down circuit configured to generate a pull down current, wherein the pull up circuit and the pull down circuit each include a plurality of temperature sensitive circuit elements; a pull up transistor serially coupled with at least one first switch, the pull up transistor and the at least one first switch coupled in parallel to the pull up circuit and together configured to generate a pull up output current; and a pull down transistor serially coupled with at least one second switch, the pull down transistor and the at least one second switch coupled in parallel to the pull down circuit and together configured to generate a pull down output current, wherein the at least one first switch and the at least one second switch are complementarily enabled in response to a temperature change.
