Process voltage and temperature detection of the silicon chip die is accomplished by PVT Sensor, an IP. It offers special characteristics like temperature and voltage probes without requiring specialized analog current and voltage signals. For real-time sensor data communication, each voltage sensor node is connected to the central controller by a single-wire digital signal. Each node has a specific enable signal that may be used to enable or inhibit the operation for power management. Each probe includes a digital interface that connects to the central controller, which preserves the sensing operation with on-chip noise and improves accuracy.
