The Core Powered PVT Sensor is an easy to integrate macro, requiring no analog power supply, and can be placed anywhere on a chip.
This highly integrated macro monitors process, voltage, and temperature variation on-chip, allowing very high precision even in untrimmed usage. Itconsumes very little power even in operational mode, and leakage power only when measurement is complete. An additional voltage sample mode is included allowing for supply voltage monitoring, and process monitor mode to assess transistor performance. The block includes a simple- to-use digital interface that works with standard core and IO level power supplies. The macro uses core and thick-oxide (1.2V and 1.2V-OD-1.5V) devices, operated on a core level power supply.
