Abstract
An apparatus including a reference resistor for use with ratiometric temperature sensing of a device to be sensed. The resistive element has a resistance dependant upon a temperature of the device to be sensed and is electrically coupled to a reference resistor. The reference resistor is maintained at a substantially constant temperature by a temperature controller. A sensor circuit is electrically coupled to the resistive element and the reference resistor to sense their electrical parameters when a current passes through them.
