ABSTRACT:
A temperature sensitive transducer circuit for use as a temperature sensor in an electronic thermometer is provided having a variable response curve or slope. A semiconductor device may be used as the primary temperature sensing component. Preferably, the semiconductor device includes two diode-effect components connected in series to circuit ground. A voltage supply may be connected to the semiconductor device through a current limiting component. A variable current limiting component may be connected across one of the diode-effect components. An amplifier component may be connected to the semiconductor device to adjust the output gain of the circuit.
