ANALOG TEMPERATURE SENSOR FOR DIGITAL BLOCKS

摘要

The disclosure provides a circuit that includes an analog control block, and a plurality of temperature sensors coupled to the analog control block. At least one temperature sensor of the plurality of temperature sensors includes a first transistor coupled to a first current source. A second transistor is coupled to a second current source and to the first transistor. The analog control block measures a local temperature from a first potential generated across the first transistor and from a second potential generated across the second transistor.
