Abstract
Disclosed is a system for measuring temperature in an integrated circuit (IC) device. The system includes a diode-based temperature sensor comprising a first plurality of diodes coupled between a power supply pin of the IC device and a ground pin of the IC device and a second plurality of diodes coupled between the power supply pin and the ground pin, and a voltage sensing circuit configured to detect a voltage difference between the first plurality of diodes and the second plurality of diodes.
