Title:
COMPARATOR, NOISE GENERATOR, AND PROBABILITY RESONATOR
Document Type and Number:
WIPO Patent Application WO/2010/041606
Kind Code:
A1
Abstract:
Provided are a hysteresis comparator and a noise generator which can significantly reduce the circuit size. Provided is also a probability resonator using the hysteresis comparator and the noise generator. When the voltage (Vs) at the both ends of a phase transition resistance element exceeds a threshold value (Vth1), the crystalline structure of the phase transition resistance element (Rv) causes a structure phase transfer to be changed from monoclinic to tetragonal and enters a relatively low-resistance state. This turns ON a transistor (Q1) and outputs a high-level output voltage (Vout) from an output terminal (Tout). On the other hand, when the voltage (Vs) applied to the both ends of the phase transition resistance element (Rv) is lower than a threshold value (Vth2), the phase transition resistance element (Rv) causes a structure phase transition to be changed from tetragonal to monoclinic and enters a relatively high-resistance state. This turns OFF the transistor (Q1) and outputs a low-level output voltage (Vout) from the output terminal (Tout).
