Abstract
Circuitry for measuring and/or monitoring device temperature may include a first node coupled to ground, and a second node and a first resistor coupled in series to ground and in parallel to the first node. A first current driven to the first node and a second current driven to the second node can be selected such that a first voltage measured at the first node and a second voltage measured at the second node are substantially equal. The circuitry may also include a third node and a second resistor coupled in series to ground. A third current driven to the third node can be selected such that a third voltage measured at the third node is substantially equal to a reference voltage. Measures of the second and third currents and measures of the first and second resistors can be used to determine device temperature.
