Abstract: A sensor system included in an integrated circuit includes multiple sensor circuits and a control circuit. Using characterization data, a model may be generated that defines a relationship between measurable parameters of the integrated circuit and an operating characteristic of the integrated circuit. The control circuit can combine, using a function included in the model, data from the multiple sensor circuits to determine a value of the operating characteristic that is more accurate than a sensor circuit configured to measure a single parameter of the integrated circuit that varies with the operating characteristic.

Abstract: A power detect circuit is disclosed. A power detect circuit includes a voltage multiplier that receives an external supply voltage and generates a second supply voltage that is greater than the former. A voltage regulator is coupled to receive the second supply voltage and outputs a regulated supply voltage. A bandgap circuit is coupled to receive the second supply voltage when a first switch is closed, and the regulated supply voltage when a second switch is closed. The bandgap circuit generates a reference voltage for the voltage regulator, as well as one or more output voltages. A comparator circuit is coupled to receive the one or more output voltages from the bandgap circuit, and may compare these one or more output voltages to the regulated supply voltage.

Abstract: A computer system may include multiple sensor circuits that monitor operation parameters of a computer system circuit in the computer system. A control circuit may use monitor signals generated by the sensor circuits to determine probabilities that the operation parameters are within corresponding ranges. The control circuit can use the determined probabilities to generate a combined probability, which can be compared to a threshold value. The operation of the computer system circuit can be adjusted by the control circuit using results of the comparison between the combined probability and the threshold value.

Abstract: The present disclosure is directed to a system implementing a sensor. A sensing system is implemented in a functional circuit block that is coupled to a global supply voltage node. The sensing system includes a power converter circuit configured to generate a regulated voltage level on a local supply node using the voltage present on the global supply voltage node. The system also includes a sensor circuit coupled to receive the regulated voltage node, wherein the sensor is configured to compare corresponding parameters of different ones of a number of subset of device at a plurality of different time points and generate a plurality of comparison results. The comparisons generate an analog signal that is proportional to the operating parameter. An analog-to-digital converter (ADC) is coupled to receive the analog signal and generate a plurality of bits corresponding thereto.
