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.
