Abstract
A temperature sensor configured to generate an output signal corresponding to a sensed and/or measured temperature includes: a diode including a cathode coupled to a ground node; a first capacitor including a first end coupled to the ground node; a switch circuit configured to connect a second end of the first capacitor to a positive voltage node or an anode of the diode according to a control signal; switch control circuitry configured to generate the control signal based on a reference voltage with a voltage of the anode; and an output signal generator configured to generate the output signal corresponding to the sensed temperature based on a frequency of the control signal.
