Abstract: An electronic device including: a reference voltage generator circuit to generate a reference voltage based on a first and second voltage, the reference voltage generator circuit including: a first current source to supply a first current to each of a first and second node; an amplifier to amplify a difference between the first voltage of the first node and the second voltage of the second node and to output a difference voltage corresponding to the amplified difference; a first bipolar junction transistor (BJT) connected to the first node; a first resistor connected to the second node; a second BJT connected between the first resistor and ground; a second resistor connected between the second node and ground; and a first transistor to be supplied with a second current from the first current source; and an adaptive cascode circuit to generate a bias voltage applied to a gate of the first transistor.

Abstract: A temperature sensing device includes a temperature-voltage converter that outputs a first voltage, having a zero temperature coefficient that does not vary with a temperature, and a second voltage having a negative temperature coefficient varying in inverse proportion to the temperature. A multiplexer alternately outputs the first voltage and the second voltage depending on a transition signal. A temperature sensor alternately receives the first voltage and the second voltage and senses the temperature depending on a ratio of the first voltage and the second voltage.
