2.2.3. Wide-Voltage Resiliency

Some NTC circuits are required to operate at different supply voltage modes, due to runtime MEP tuning, ultra-low power requirements, or speed constraints (super-threshold). When a task with specific timing constraints executes on the NTC circuit, the supply voltage may be increased to the super-threshold region to meet the performance constraints. However, this brings reliability issues associated with super-threshold voltage, such as aging, into consideration as the circuit may operate in that mode for some time. For example, an IoT edge device may be assigned to process some data within a specific amount of time and send them to an IoT gateway. Therefore, it is necessary to take the aging issues into consideration if a device is expected to operate over a wide-voltage range as this may have deteriorating impact on the device operation when it is switched back to the NTV region or even in the super-threshold voltage region.
