A Schmitt trigger's hysteresis is established by standard and non-standard MOSFETs having different (lower/higher) threshold voltages. For example, a standard n-channel transistor having a relatively low threshold voltage (e.g., 1V) sets the lower trigger switching voltage, and a non-standard n-channel transistor (e.g., an n-channel source/drain and a polysilicon gate doped with a p-type dopant) exhibits a relatively high threshold voltage (e.g., 2V) that sets the higher trigger switching voltage. An output control circuit generates the Schmitt trigger's digital output signal based on the on/off states of the two (non-standard and standard) MOSFETs, whereby the changes digital output signal between two values when the analog input signal falls below the lower threshold voltage (i.e., when both MOSFETs are turned on/off) and rises above the higher threshold voltage (i.e., when both MOSFETs are turned off/on). Self-resetting and other circuits utilize the Schmitt trigger to facilitate, e.g., high dynamic range image sensor pixels.
