Abstract:
1. A circuit for measuring a discontinuous MIT (metal-insulator transition) of an MIT element comprising: a to-be-measured object unit including the MIT element in which a discontinuous MIT occurs at the transition voltage thereof; a power supply unit applying a predetermined pulse current or voltage signal to the to-be-measured object unit; a measurement unit measuring the discontinuous MIT of the MIT element; and a controller controlling the power supply unit and the measurement unit, wherein the to-be-measured object unit comprises a protection resistor connected in series with the MIT element, the power supply unit comprises a transistor controlled by a pulse current or voltage signal and an input power supply applying a fixed voltage to the to-be-measured object unit, and the measurement unit comprises a sample holder and an ADC converting the output signal of the sample holder into a digital signal.
