  • Method and apparatus for temperature adjusted control of BATFET current sensing
    Patent number: 9000750
    Abstract: A method and apparatus for providing a temperature sensing loop used in connection with a current sensing component, such as a BATFET, in order to compensate for variations in the BATFET's resistance due to temperature variations. The temperature sensing loop detects a temperature of the BATFET and regulates the gate voltage of the BATFET based on the detected temperature in order to compensate for changes in the BATFET's resistance. The temperature sensing feedback loop maintains the BATFET at a constant resistance for current sensing through negative feedback control. The BATFET and temperature sensing loop can be provided as components of an on-chip fuel gauging application for a UE.
