Assignee: STMICROELECTRONICS S.R.L.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 31:
32. A temperature sensing circuit, comprising:
a first MOS transistor having a first drain, a first source, a first gate and a first body;
wherein the first gate is electrically shorted to the first drain;
wherein the first drain is coupled to a supply voltage node;
wherein the first MOS transistor has a negative temperature coefficient drain-source resistance; and
a second MOS transistor having a second drain, a second source, a second gate and a second body;
wherein the second gate is electrically shorted to the first source at an output terminal configured to generate a positive temperature coefficient output voltage;
wherein the first body and second body are each electrically shorted to a ground node; and
wherein the second source and second drain are each electrically shorted to the ground node.
