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.
