Original Abstract Submitted
various techniques for implementing resistive temperature sensors that rely on the resistors' temperature sensitivity to provide temperature sensing are disclosed. temperature sensitive resistors may be implemented in a resistor stack in combination with a resistor stack of resistors that are relatively temperature indifferent. various temperature sensor circuits implementing these temperature sensitive resistors are also disclosed. a temperature sensor circuit may implement the temperature sensitive resistors along with the resistors that are relatively stable with temperature to output a voltage signal that is indicative of the temperature sensed by the circuit. in some instances, the signal from the temperature sensitive resistors is increased through the use of a feedback resistor loop.
