ABSTRACT:
An input receiver with hysteresis including a differential sense amplifier, a reference circuit having a reference node providing a reference signal at a nominal threshold voltage level, and a switching stack device. The amplifier has a first input which receives an input signal, a second input coupled to the reference node, and an output which provides an output signal having first and second states indicative of the input signal. The switching stack device operates to adjust the reference signal based on the output signal between upper and lower threshold levels in an opposite direction of the input signal. The reference circuit may be a voltage divider that divides a power voltage signal to develop the reference signal. The switching stack device may include a P-channel device and an N-channel device coupled to the voltage divider to adjust the threshold voltage level of the reference signal.
