Abstract
A threshold amplifier receives a logic supply voltage and a ground voltage and includes a Schmitt trigger comprising an inverter stage and a hysteresis stage connected to the inverter stage for setting a high and a low hysteresis threshold. A disabling circuit disables the hysteresis stage as a function of a level of the logic supply voltage. The threshold amplifier further includes a detection circuit for detecting the level of the logic supply voltage with respect to a detection threshold, and for activating the disabling circuit for disabling the hysteresis stage when the level of the logic supply voltage is below the detection threshold.
