Abstract
The temperature sensing system comprises a solid state temperature sensor having at least one junction for developing a junction voltage in response to a current conducted through the solid state temperature sensor. The voltage is at least partially determined by temperature of the solid state temp. sensor. A current source generates the current conducted through the solid state temp. sensor. The current is conducted in two current levels. Two voltage value storage devices store values of the junction voltage in response to the current levels. A integrator receives signal and responds to the stored junction voltages. The integrated are direction to produce an output of the integrator an integration signal proportional to a difference between the junction voltages. In response to the integration signal a temp. signal indicative of the temp. sensed by the temp. sensor is provided.
