Abstract: Various embodiments provide for a level shifter with sub-threshold voltage functionality, which permits the level shifter to operate even when a voltage supply to the level shifter falls below a normal operational voltage range of one or more devices (e.g., transistors) within the level shifter. A level shift of an embodiment may operate when a voltage supply falls below a normal operational range in order to save power, which can be useful with respect to battery-operated devices, such an Internet of Things (IoT) sensor.
