Abstract
Described embodiments provide circuits, systems and methods for generating a sensing signal in response to the ambient condition, comparing the sensing signal to a threshold hysteresis range to generate a digital signal, and upon powering on the sensor, determining whether the sensing signal is within the threshold hysteresis range and, if the sensing signal is within the threshold hysteresis range, setting the digital signal to a predetermined level based on a hysteresis restoration state associated with sensor before the sensor is powered off.
