Embodiment 1
[0012] The first embodiment is a performance test device based on antiferroelectric materials, including a signal frequency acquisition circuit, a detection calibration circuit, and a filter compensation circuit. The signal frequency acquisition circuit selects the signal frequency collector J1 with the model of SJ-ADC to collect data based on antiferroelectric materials. The electrical material performance test device controls the frequency of the data signal received by the terminal, and uses a clamping circuit composed of diode D2 and diode D3 to clamp the signal within 0-+5V. The detection and calibration circuit is divided into two reception signal frequency acquisition circuits Output signal, one way uses capacitor C2 to filter the noise of low-frequency signal, while using op amp AR1 and op amp AR2 to form a detection circuit to filter out the peak signal, the second way uses transistor Q1 and voltage stabilizer D7 composed of a transistor voltage stabilizer circuit At th...
Embodiment 2
[0015] In the second embodiment, on the basis of the first embodiment, the filter compensation circuit uses the inductor L2, the resistor R17, the capacitor C7, and the capacitor C8 to form the clutter in the output signal of the filter circuit, and then outputs the clutter to filter out the clutter in the signal. That is to compensate the data signal potential received by the control terminal in the antiferroelectric material-based performance test device to prevent signal attenuation. One end of the inductor L2 is connected to one end of the resistor R16, resistor R17, and capacitor C7, and the other end of the resistor R16 is connected to the transistor Q5. Emitter, the other end of inductor L2 is connected to one end of inductor L3 and one end of capacitor C8, the other ends of resistor R17, capacitor C7, and capacitor C8 are grounded, the other end of inductor L3 is connected to one end of resistor R18, and the other end of resistor R18 is connected to the signal Output por...
