Abstract
A temperature measuring circuit includes: a first switch circuit configured to charge a capacitor upon receiving a first control signal and discharge the capacitor upon receiving a second control signal; a control circuit configured to set a control signal at a second control signal in response to an output voltage indicating that an inter-terminal voltage is higher than a first reference voltage, set the control signal at the first control signal in response to the output voltage indicating that the inter-terminal voltage is lower than a second reference voltage, and set the control signal at the second control signal in response to the output voltage indicating that the inter-terminal voltage is higher than a third reference voltage; a counter circuit configured to count a frequency of the control signal; and a temperature obtaining unit configured to obtain the temperature based on the frequency.
