An electronic device can include a temperature sensor. The temperature sensor can include a drain electrode including drain fingers spaced apart from the source fingers; a source electrode including source fingers spaced apart from the drain fingers; and a gate electrode including a runner, gate fingers and a conductive bridge. In an embodiment, the runner includes a first portion and a second portion spaced apart from the first portion, the gate fingers are coupled to the runner and each gate finger is disposed between a pair of the source and drain fingers. The conductive bridge connects at least two gate fingers, wherein the conductive bridge is along a conduction path between the first and second portions of the runner. Designs for the temperature sensor may provide a more accurate temperature measurement reflective of a transistor within the electronic device.
