Patent ID: 6949968

Claim:
An apparatus comprising: a temperature sensor block that is arranged to provide a temperature signal (TEMP) that is responsive to changes in an operating temperature (T); a level shifter block that is arranged to: receive the temperature signal (TEMP), and provide a level shifted temperature signal (TEMPLS) that is related to the temperature signal (TEMP) by a DC level shift; a gain block that is arranged to: receive the level shifted temperature signal (TEMPLS) and provide an output signal (OUT) that is related to the level shifted temperature signal (TEMPLS) according to a gain factor (G); an analog-to-digital converter (ADC) block that is arranged to: receive the output signal (OUT), and provide a control signal (CTL 2 ) that is related to an operating temperature; and a control logic block that is arranged to: receive the control signal (CTL 2 ) and provide another control signal (CTL 1 ) to at least one of the level shifter block and the gain block such that a dynamic range associated with the temperature sensitivity of the apparatus is extended.
