  • Patent number: 12580028
    Abstract: A digital thermometer includes a first oscillator to generate a first clock signal, wherein a period of this clock signal remains constant in view of temperature changes of the apparatus and a first counter coupled to the first oscillator, this counter to count a fixed number of cycles of the first clock signal associated with a measurement period. The digital thermometer further includes a second oscillator to generate a second clock signal, wherein a period of this clock signal varies with temperature changes and a second counter coupled to the second oscillator, this counter to generate an output representing a count of a number of cycles of the second clock signal that occur during the measurement period. Additionally, the digital thermometer includes calibration circuitry coupled to the second counter, the calibration circuitry to generate, based on the output of the second counter, a value representing the temperature of the apparatus.

  • Publication number: 20230017305
    Abstract: A variety of applications can include apparatus or methods that provide a well ring for resistive ground power domain segregation. The well ring can be implemented as a n-well in a p-type substrate. Resistive separation between ground domains can be generated by biasing a n-well ring to an external supply voltage. This approach can provide a procedure, from a process standpoint, that provides relatively high flexibility to design for chip floor planning and simulation, while providing sufficient noise rejection between independent ground power domains when correctly sized. Significant noise rejection between ground power domains can be attained.
