Abstract

PURPOSE:To manufacture a temperature detecting device whose output is digital amount and which can be integrated wholly, by conveting a temperature signal into frequency signals and comparing a frequency signal with a reference frequency. CONSTITUTION:Voltages corresponding to temperatures are generated by a temperature detecting circuit, and the output current of a volt-ampere converting circuit is controlled by the voltages, and, moreover, the frequency of an oscillating circuit is changed by the voltages. In this way, frequencies corresponding to the temperatures are generated. The frequencies thus generated are compared with a reference frequency from a reference oscillating section, and thus, the detection of temperatures is performed. For example, a temperature detecting circuit 13 which is stable to the variation in the supply voltage and which generates different voltages in accordance with the change in the temperature, a potential and current converting circuit 14 which generates electric currents corresponding to the above- mentioned voltage irrespectively of the supply voltage, an oscillating circuit 15 which widely changes the frequency in accordance with the above-mentioned electric current, and a shaping circuit 16 are connected to each other as shown in the diagram, and the output T is compared with the frequency of a standard oscillator in accordance with an oscillation start signal VSW. The temperature detector of digital output is obtained in this way.
