Abstract: A temperature sensing device including a first temperature sensor having a first resistor and a first capacitor and generating a first voltage applied to at least one of the first resistor or the first capacitor based on a first clock signal and a second clock signal generated by delaying the first clock signal, a second temperature sensor having a second resistor and a second capacitor and generating a second voltage applied to at least one of the second resistor or the second capacitor based on the first and second clock signals, a controller generating code data based on the first voltage and the second voltage and generating a control signal based on the code data, and a delay locked loop circuit delaying the first clock signal based on the control signal to generate the second clock signal may be provided.
