==TEMPERATURE SENSOR CIRCUITS AND CONTROL CIRCUITS AND METHOD FOR TEMPERATURE SENSOR CIRCUITS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18150772 titled 'TEMPERATURE SENSOR CIRCUITS AND CONTROL CIRCUITS AND METHOD FOR TEMPERATURE SENSOR CIRCUITS

==Simplified Explanation==

The patent application describes a temperature sensor circuit, control circuit, and control method.
* The temperature sensor circuit includes a temperature sensor and a control circuit.
* The control circuit is connected to the temperature sensor and consists of a current source, a sampling circuit, and a computing circuit.
* The current source supplies a first current and a second current to the temperature sensor at different time periods.
* The sampling circuit collects and stores a first voltage information and a second voltage information from the temperature sensor when the first and second currents are provided.
* The computing circuit is connected to the sampling circuit and calculates a sensing result based on the difference between the second voltage information and the first voltage information.


==Original Abstract Submitted==

A temperature sensor circuit, a control circuit, and a control method are provided. The temperature sensor circuit comprises a temperature sensor and a control circuit. The control circuit is coupled to the temperature sensor and comprises a current source, a sampling circuit, and a computing circuit. The current source is configured to provide a first current and a second current to the temperature sensor in different time periods. The sampling circuit is coupled to the temperature sensor and configured to obtain and store a first voltage information and a second voltage information from the temperature sensor when the first current and second current are respectively provided. The computing circuit is coupled to the sampling circuit and configured to generate a sensing result corresponding to a difference of subtracting the second voltage information from the first voltage information.
