Abstract
A system and method for sensing the temperature of a device. This includes the establishment of a programmable current from an on-chip source, which in turn is used to produce a temperature dependent voltage from a temperature dependent resistive device. The temperature dependent resistive device is thermally coupled to a device for which the temperature is to be sensed. The temperature dependent voltage produced is converted to a digital value and equated to the temperature of the device.
