TEMPERATURE SENSING BASED ON METAL RAILS WITH DIFFERENT THERMAL-RESISTANCE COEFFICIENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18170401 titled 'TEMPERATURE SENSING BASED ON METAL RAILS WITH DIFFERENT THERMAL-RESISTANCE COEFFICIENTS

Simplified Explanation

The patent application describes a device and method for sensing temperature.

  • The device includes a first resistor with a first metal rail in a first layer, which has a specific thermal-resistance coefficient.
  • The device also includes a second resistor with a second metal rail in a second layer above the first layer, which has a different thermal-resistance coefficient.
  • A sensing circuit is connected to both resistors and is designed to determine the temperature based on the thermal-resistance coefficients of the metal rails.


Original Abstract Submitted

Disclosed herein are related to a device and a method for sensing a temperature. In one aspect, the device includes a first resistor including a first metal rail in a first layer. The first metal rail may have a first thermal-resistance coefficient. In one aspect, the device includes a second resistor including a second metal rail in a second layer above the first layer along a direction. The second metal rail may have a second thermal-resistance coefficient. In one aspect, the device includes a sensing circuit coupled to the first resistor and the second resistor. The sensing circuit may be configured to determine a temperature, according to the first metal rail having the first thermal-resistance coefficient and the second metal rail having the second thermal-resistance coefficient.
