ABSTRACT:
A temperature sensor and device and system including same, comprise a switched capacitor circuit configured to generate a noise voltage in response to switching and circuitry configured to generate a relative temperature output signal proportional to an absolute temperature output signal in response to the noise voltage. The device includes a temperature sensor, temperature sensitive device logic and temperature compensation logic configured to receive the absolute temperature and generate an adjustment signal to adapt the temperature sensitive device logic in response thereto. A related method for sensing temperature includes amplifying a noise voltage from a switched capacitor circuit in a plurality of parallel amplifier channels and removing amplifier noise from each of the plurality of parallel amplifier channels to form a relative output signal proportional to an absolute temperature.
