ABSTRACT:
A hysteresis comparing device with constant hysteresis width and the method thereof, which can respectively receive a first signal and a second signal and can output a digital signal. The hysteresis comparing device includes a threshold voltage generator, a multiplexer, and a next stage comparator. The threshold voltage generator is used to receive the first signal and output an upper threshold voltage and a lower threshold voltage. The multiplexer is used to receive the upper threshold voltage and the lower threshold voltage, and output a multiplexing signal according to the digital signal. The multiplexing signal is either the upper threshold voltage or the lower threshold voltage. The next stage comparator has one terminal used to receive the multiplexing signal, and another terminal used to receive the second signal. The next stage comparator outputs the digital signal. The hysteresis comparing device with constant hysteresis width can suppress the effect from the glitch. Also and, under the affection of the environment, a constant hysteresis width can still provided, so that the hysteresis, comparing device can judge the received signals with higher precision.
